It reads a stream of Ansi characters and produces the appropriate function calls. The results of the function calls are platform dependent. - -For example the parser might receive "ESC, [, A" as a stream of three characters. This is the code for Cursor Up (http://www.vt100.net/docs/vt510-rm/CUU). The parser then calls the cursor up function (CUU()) on an event handler. The event handler determines what platform specific work must be done to cause the cursor to move up one position. - -The parser (parser.go) is a partial implementation of this state machine (http://vt100.net/emu/vt500_parser.png). There are also two event handler implementations, one for tests (test_event_handler.go) to validate that the expected events are being produced and called, the other is a Windows implementation (winterm/win_event_handler.go). - -See parser_test.go for examples exercising the state machine and generating appropriate function calls. - ------ -This project has adopted the [Microsoft Open Source Code of Conduct](https://opensource.microsoft.com/codeofconduct/).

The first step is to parse a specifier into a matcher: -// -// m, err := Parse("linux") -// if err != nil { ... } -// -// Once you have a matcher, use it to match against the platform declared by a -// component, typically from an image or runtime.

Typically, this will be -// images and runtimes that should make these declaring which platform they -// support specifically. This looks roughly as follows: -// -// type Platform struct { -// Architecture string -// OS string -// Variant string -// } -// -// Most images and runtimes should at least set Architecture and OS, according -// to their GOARCH and GOOS values, respectively (follow the OCI image -// specification when in doubt). ARM should set variant under certain -// discussions, which are outlined below. -// -// Platform Specifiers -// -// While the OCI platform specifications provide a tool for components to -// specify structured information, user input typically doesn't need the full -// context and much can be inferred. To solve this problem, we introduced -// "specifiers". A specifier has the format -// `||/[/]`. The user can provide either the -// operating system or the architecture or both. -// -// An example of a common specifier is `linux/amd64`. If the host has a default -// of runtime that matches this, the user can simply provide the component that -// matters. For example, if a image provides amd64 and arm64 support, the -// operating system, `linux` can be inferred, so they only have to provide -// `arm64` or `amd64`. Similar behavior is implemented for operating systems, -// where the architecture may be known but a runtime may support images from -// different operating systems. -// -// Normalization -// -// Because not all users are familiar with the way the Go runtime represents -// platforms, several normalizations have been provided to make this package -// easier to user. -// -// The following are performed for architectures: -// -// Value Normalized -// aarch64 arm64 -// armhf arm -// armel arm/v6 -// i386 386 -// x86_64 amd64 -// x86-64 amd64 -// -// We also normalize the operating system `macos` to `darwin`. -// -// ARM Support -// -// To qualify ARM architecture, the Variant field is used to qualify the arm -// version. The most common arm version, v7, is represented without the variant -// unless it is explicitly provided. This is treated as equivalent to armhf.

This was -primarily focused on implementing the [new registry -API](https://github.com/docker/distribution/blob/master/docs/spec/api.md), -with a focus on security and performance. - -Following from the Distribution project goals above, we have a set of goals -for registry v2 that we would like to follow in the design. New features -should be compared against these goals. - -#### Data Storage and Distribution First - -The registry's first goal is to provide a reliable, consistent storage -location for Docker images. The registry should only provide the minimal -amount of indexing required to fetch image data and no more. - -This means we should be selective in new features and API additions, including -those that may require expensive, ever growing indexes. Requests should be -servable in "constant time". - -#### Content Addressability - -All data objects used in the registry API should be content addressable. -Content identifiers should be secure and verifiable. This provides a secure, -reliable base from which to build more advanced content distribution systems. - -#### Content Agnostic - -In the past, changes to the image format would require large changes in Docker -and the Registry. By decoupling the distribution and image format, we can -allow the formats to progress without having to coordinate between the two. -This means that we should be focused on decoupling Docker from the registry -just as much as decoupling the registry from Docker. Such an approach will -allow us to unlock new distribution models that haven't been possible before. - -We can take this further by saying that the new registry should be content -agnostic. The registry provides a model of names, tags, manifests and content -addresses and that model can be used to work with content. - -#### Simplicity - -The new registry should be closer to a microservice component than its -predecessor. This means it should have a narrower API and a low number of -service dependencies. It should be easy to deploy. - -This means that other solutions should be explored before changing the API or -adding extra dependencies. If functionality is required, can it be added as an -extension or companion service. - -#### Extensibility - -The registry should provide extension points to add functionality. By keeping -the scope narrow, but providing the ability to add functionality. - -Features like search, indexing, synchronization and registry explorers fall -into this category. No such feature should be added unless we've found it -impossible to do through an extension. - -#### Active Feature Discussions - -The following are feature discussions that are currently active. - -If you don't see your favorite, unimplemented feature, feel free to contact us -via IRC or the mailing list and we can talk about adding it. The goal here is -to make sure that new features go through a rigid design process before -landing in the registry. - -##### Proxying to other Registries - -A _pull-through caching_ mode exists for the registry, but is restricted from -within the docker client to only mirror the official Docker Hub. This functionality -can be expanded when image provenance has been specified and implemented in the -distribution project. - -##### Metadata storage - -Metadata for the registry is currently stored with the manifest and layer data on -the storage backend. While this is a big win for simplicity and reliably maintaining -state, it comes with the cost of consistency and high latency. The mutable registry -metadata operations should be abstracted behind an API which will allow ACID compliant -storage systems to handle metadata. - -##### Peer to Peer transfer - -Discussion has started here: https://docs.google.com/document/d/1rYDpSpJiQWmCQy8Cuiaa3NH-Co33oK_SC9HeXYo87QA/edit - -##### Indexing, Search and Discovery - -The original registry provided some implementation of search for use with -private registries. Support has been elided from V2 since we'd like to both -decouple search functionality from the registry. The makes the registry -simpler to deploy, especially in use cases where search is not needed, and -let's us decouple the image format from the registry. - -There are explorations into using the catalog API and notification system to -build external indexes. The current line of thought is that we will define a -common search API to index and query docker images. Such a system could be run -as a companion to a registry or set of registries to power discovery. - -The main issue with search and discovery is that there are so many ways to -accomplish it. There are two aspects to this project. The first is deciding on -how it will be done, including an API definition that can work with changing -data formats. The second is the process of integrating with `docker search`. -We expect that someone attempts to address the problem with the existing tools -and propose it as a standard search API or uses it to inform a standardization -process. Once this has been explored, we integrate with the docker client. - -Please see the following for more detail: - -- https://github.com/docker/distribution/issues/206 - -##### Deletes - -> __NOTE:__ Deletes are a much asked for feature. Before requesting this -feature or participating in discussion, we ask that you read this section in -full and understand the problems behind deletes. - -While, at first glance, implementing deleting seems simple, there are a number -mitigating factors that make many solutions not ideal or even pathological in -the context of a registry. The following paragraph discuss the background and -approaches that could be applied to arrive at a solution. - -The goal of deletes in any system is to remove unused or unneeded data. Only -data requested for deletion should be removed and no other data. Removing -unintended data is worse than _not_ removing data that was requested for -removal but ideally, both are supported. Generally, according to this rule, we -err on holding data longer than needed, ensuring that it is only removed when -we can be certain that it can be removed. With the current behavior, we opt to -hold onto the data forever, ensuring that data cannot be incorrectly removed. - -To understand the problems with implementing deletes, one must understand the -data model. All registry data is stored in a filesystem layout, implemented on -a "storage driver", effectively a _virtual file system_ (VFS). The storage -system must assume that this VFS layer will be eventually consistent and has -poor read- after-write consistency, since this is the lower common denominator -among the storage drivers. This is mitigated by writing values in reverse- -dependent order, but makes wider transactional operations unsafe. - -Layered on the VFS model is a content-addressable _directed, acyclic graph_ -(DAG) made up of blobs. Manifests reference layers. Tags reference manifests. -Since the same data can be referenced by multiple manifests, we only store -data once, even if it is in different repositories. Thus, we have a set of -blobs, referenced by tags and manifests. If we want to delete a blob we need -to be certain that it is no longer referenced by another manifest or tag. When -we delete a manifest, we also can try to delete the referenced blobs. Deciding -whether or not a blob has an active reference is the crux of the problem. - -Conceptually, deleting a manifest and its resources is quite simple. Just find -all the manifests, enumerate the referenced blobs and delete the blobs not in -that set. An astute observer will recognize this as a garbage collection -problem. As with garbage collection in programming languages, this is very -simple when one always has a consistent view. When one adds parallelism and an -inconsistent view of data, it becomes very challenging. - -A simple example can demonstrate this. Let's say we are deleting a manifest -_A_ in one process. We scan the manifest and decide that all the blobs are -ready for deletion. Concurrently, we have another process accepting a new -manifest _B_ referencing one or more blobs from the manifest _A_. Manifest _B_ -is accepted and all the blobs are considered present, so the operation -proceeds. The original process then deletes the referenced blobs, assuming -they were unreferenced. The manifest _B_, which we thought had all of its data -present, can no longer be served by the registry, since the dependent data has -been deleted. - -Deleting data from the registry safely requires some way to coordinate this -operation. The following approaches are being considered: - -- _Reference Counting_ - Maintain a count of references to each blob. This is - challenging for a number of reasons: 1. maintaining a consistent consensus - of reference counts across a set of Registries and 2. Building the initial - list of reference counts for an existing registry. These challenges can be - met with a consensus protocol like Paxos or Raft in the first case and a - necessary but simple scan in the second.. -- _Lock the World GC_ - Halt all writes to the data store. Walk the data store - and find all blob references. Delete all unreferenced blobs. This approach - is very simple but requires disabling writes for a period of time while the - service reads all data. This is slow and expensive but very accurate and - effective. -- _Generational GC_ - Do something similar to above but instead of blocking - writes, writes are sent to another storage backend while reads are broadcast - to the new and old backends. GC is then performed on the read-only portion. - Because writes land in the new backend, the data in the read-only section - can be safely deleted. The main drawbacks of this approach are complexity - and coordination. -- _Centralized Oracle_ - Using a centralized, transactional database, we can - know exactly which data is referenced at any given time. This avoids - coordination problem by managing this data in a single location. We trade - off metadata scalability for simplicity and performance. This is a very good - option for most registry deployments. This would create a bottleneck for - registry metadata. However, metadata is generally not the main bottleneck - when serving images. - -Please let us know if other solutions exist that we have yet to enumerate. -Note that for any approach, implementation is a massive consideration. For -example, a mark-sweep based solution may seem simple but the amount of work in -coordination offset the extra work it might take to build a _Centralized -Oracle_. We'll accept proposals for any solution but please coordinate with us -before dropping code. - -At this time, we have traded off simplicity and ease of deployment for disk -space. Simplicity and ease of deployment tend to reduce developer involvement, -which is currently the most expensive resource in software engineering. Taking -on any solution for deletes will greatly effect these factors, trading off -very cheap disk space for a complex deployment and operational story. - -Please see the following issues for more detail: - -- https://github.com/docker/distribution/issues/422 -- https://github.com/docker/distribution/issues/461 -- https://github.com/docker/distribution/issues/462 - -### Distribution Package - -At its core, the Distribution Project is a set of Go packages that make up -Distribution Components.

The code is actually valid, but it looks probably more weird: `v1_20.CallFunction`. - -For instance, if you want to modify a type that was available in the version `1.21` of the API but it will have different fields in the version `1.22`, you want to create a new package under `api/types/versions/v1p21`. diff --git a/vendor/github.com/docker/docker/api/types/versions/compare.go b/vendor/github.com/docker/docker/api/types/versions/compare.go deleted file mode 100644 index 8ccb0aa..0000000 --- a/vendor/github.com/docker/docker/api/types/versions/compare.go +++ /dev/null @@ -1,62 +0,0 @@ -package versions // import "github.com/docker/docker/api/types/versions" - -import ( - "strconv" - "strings" -) - -// compare compares two version strings -// returns -1 if v1 < v2, 1 if v1 > v2, 0 otherwise. -func compare(v1, v2 string) int { - var ( - currTab = strings.Split(v1, ".") - otherTab = strings.Split(v2, ".") - ) - - max := len(currTab) - if len(otherTab) > max { - max = len(otherTab) - } - for i := 0; i < max; i++ { - var currInt, otherInt int - - if len(currTab) > i { - currInt, _ = strconv.Atoi(currTab[i]) - } - if len(otherTab) > i { - otherInt, _ = strconv.Atoi(otherTab[i]) - } - if currInt > otherInt { - return 1 - } - if otherInt > currInt { - return -1 - } - } - return 0 -} - -// LessThan checks if a version is less than another -func LessThan(v, other string) bool { - return compare(v, other) == -1 -} - -// LessThanOrEqualTo checks if a version is less than or equal to another -func LessThanOrEqualTo(v, other string) bool { - return compare(v, other) <= 0 -} - -// GreaterThan checks if a version is greater than another -func GreaterThan(v, other string) bool { - return compare(v, other) == 1 -} - -// GreaterThanOrEqualTo checks if a version is greater than or equal to another -func GreaterThanOrEqualTo(v, other string) bool { - return compare(v, other) >= 0 -} - -// Equal checks if a version is equal to another -func Equal(v, other string) bool { - return compare(v, other) == 0 -} diff --git a/vendor/github.com/docker/docker/api/types/volume.go b/vendor/github.com/docker/docker/api/types/volume.go deleted file mode 100644 index b5ee96a..0000000 --- a/vendor/github.com/docker/docker/api/types/volume.go +++ /dev/null @@ -1,69 +0,0 @@ -package types - -// This file was generated by the swagger tool. -// Editing this file might prove futile when you re-run the swagger generate command - -// Volume volume -// swagger:model Volume -type Volume struct { - - // Date/Time the volume was created. - CreatedAt string `json:"CreatedAt,omitempty"` - - // Name of the volume driver used by the volume. - // Required: true - Driver string `json:"Driver"` - - // User-defined key/value metadata. - // Required: true - Labels map[string]string `json:"Labels"` - - // Mount path of the volume on the host. - // Required: true - Mountpoint string `json:"Mountpoint"` - - // Name of the volume. - // Required: true - Name string `json:"Name"` - - // The driver specific options used when creating the volume. - // Required: true - Options map[string]string `json:"Options"` - - // The level at which the volume exists.

Ultimately, this document should -be the starting point of further refinements to the algorithm and its future -versions. - -## Concept - -The checksum mechanism must ensure the integrity and assurance of the -filesystem payload. - -## Checksum Algorithm Profile - -A checksum mechanism must define the following operations and attributes: - -* Associated hashing cipher - used to checksum each file payload and attribute - information. -* Checksum list - each file of the filesystem archive has its checksum - calculated from the payload and attributes of the file. The final checksum is - calculated from this list, with specific ordering. -* Version - as the algorithm adapts to requirements, there are behaviors of the - algorithm to manage by versioning. -* Archive being calculated - the tar archive having its checksum calculated - -## Elements of TarSum checksum - -The calculated sum output is a text string. The elements included in the output -of the calculated sum comprise the information needed for validation of the sum -(TarSum version and hashing cipher used) and the expected checksum in hexadecimal -form. - -There are two delimiters used: -* '+' separates TarSum version from hashing cipher -* ':' separates calculation mechanics from expected hash - -Example: - -``` - "tarsum.v1+sha256:220a60ecd4a3c32c282622a625a54db9ba0ff55b5ba9c29c7064a2bc358b6a3e" - | | \ | - | | \ | - |_version_|_cipher__|__ | - | \ | - |_calculation_mechanics_|______________________expected_sum_______________________| -``` - -## Versioning - -Versioning was introduced [0] to accommodate differences in calculation needed, -and ability to maintain reverse compatibility. - -The general algorithm will be describe further in the 'Calculation'. - -### Version0 - -This is the initial version of TarSum. - -Its element in the TarSum checksum string is `tarsum`. - -### Version1 - -Its element in the TarSum checksum is `tarsum.v1`. - -The notable changes in this version: -* Exclusion of file `mtime` from the file information headers, in each file - checksum calculation -* Inclusion of extended attributes (`xattrs`. Also seen as `SCHILY.xattr.` prefixed Pax - tar file info headers) keys and values in each file checksum calculation - -### VersionDev - -*Do not use unless validating refinements to the checksum algorithm* - -Its element in the TarSum checksum is `tarsum.dev`. - -This is a floating place holder for a next version and grounds for testing -changes. The methods used for calculation are subject to change without notice, -and this version is for testing and not for production use. - -## Ciphers - -The official default and standard hashing cipher used in the calculation mechanic -is `sha256`. This refers to SHA256 hash algorithm as defined in FIPS 180-4. - -Though the TarSum algorithm itself is not exclusively bound to the single -hashing cipher `sha256`, support for alternate hashing ciphers was later added -[1]. Use cases for alternate cipher could include future-proofing TarSum -checksum format and using faster cipher hashes for tar filesystem checksums. - -## Calculation - -### Requirement - -As mentioned earlier, the calculation is such that it takes into consideration -the lifecycle of the tar archive. In that the tar archive is not an immutable, -permanent artifact. Otherwise options like relying on a known hashing cipher -checksum of the archive itself would be reliable enough. The tar archive of the -filesystem is used as a transportation medium for Docker images, and the -archive is discarded once its contents are extracted. Therefore, for consistent -validation items such as order of files in the tar archive and time stamps are -subject to change once an image is received. - -### Process - -The method is typically iterative due to reading tar info headers from the -archive stream, though this is not a strict requirement. - -#### Files - -Each file in the tar archive have their contents (headers and body) checksummed -individually using the designated associated hashing cipher. The ordered -headers of the file are written to the checksum calculation first, and then the -payload of the file body. - -The resulting checksum of the file is appended to the list of file sums. The -sum is encoded as a string of the hexadecimal digest. Additionally, the file -name and position in the archive is kept as reference for special ordering. - -#### Headers - -The following headers are read, in this -order ( and the corresponding representation of its value): -* 'name' - string -* 'mode' - string of the base10 integer -* 'uid' - string of the integer -* 'gid' - string of the integer -* 'size' - string of the integer -* 'mtime' (_Version0 only_) - string of integer of the seconds since 1970-01-01 00:00:00 UTC -* 'typeflag' - string of the char -* 'linkname' - string -* 'uname' - string -* 'gname' - string -* 'devmajor' - string of the integer -* 'devminor' - string of the integer - -For >= Version1, the extended attribute headers ("SCHILY.xattr." prefixed pax -headers) included after the above list. These xattrs key/values are first -sorted by the keys. - -#### Header Format - -The ordered headers are written to the hash in the format of - - "{.key}{.value}" - -with no newline. - -#### Body - -After the order headers of the file have been added to the checksum for the -file, the body of the file is written to the hash. - -#### List of file sums - -The list of file sums is sorted by the string of the hexadecimal digest. - -If there are two files in the tar with matching paths, the order of occurrence -for that path is reflected for the sums of the corresponding file header and -body. - -#### Final Checksum - -Begin with a fresh or initial state of the associated hash cipher. If there is -additional payload to include in the TarSum calculation for the archive, it is -written first. Then each checksum from the ordered list of file sums is written -to the hash. - -The resulting digest is formatted per the Elements of TarSum checksum, -including the TarSum version, the associated hash cipher and the hexadecimal -encoded checksum digest. - -## Security Considerations - -The initial version of TarSum has undergone one update that could invalidate -handcrafted tar archives. The tar archive format supports appending of files -with same names as prior files in the archive. The latter file will clobber the -prior file of the same path. Due to this the algorithm now accounts for files -with matching paths, and orders the list of file sums accordingly [3]. - -## Footnotes - -* [0] Versioning https://github.com/docker/docker/commit/747f89cd327db9d50251b17797c4d825162226d0 -* [1] Alternate ciphers https://github.com/docker/docker/commit/4e9925d780665149b8bc940d5ba242ada1973c4e -* [2] Tar http://en.wikipedia.org/wiki/Tar_%28computing%29 -* [3] Name collision https://github.com/docker/docker/commit/c5e6362c53cbbc09ddbabd5a7323e04438b57d31 - -## Acknowledgments - -Joffrey F (shin-) and Guillaume J.

Namespace and Subsystem - -This package provides you with a namespace type that allows you to specify the same namespace and subsystem for your metrics. - -```go -ns := metrics.NewNamespace("engine", "daemon", metrics.Labels{ - "version": dockerversion.Version, - "commit": dockerversion.GitCommit, -}) -``` - -In the example above we are creating metrics for the Docker engine's daemon package. -`engine` would be the namespace in this example where `daemon` is the subsystem or package where we are collecting the metrics. - -A namespace also allows you to attach constant labels to the metrics such as the git commit and version that it is collecting. - -2. Declaring your Metrics - -Try to keep all your metric declarations in one file. -This makes it easy for others to see what constant labels are defined on the namespace and what labels are defined on the metrics when they are created. - -3. Use labels instead of multiple metrics - -Labels allow you to define one metric such as the time it takes to perform a certain action on an object. -If we wanted to collect timings on various container actions such as create, start, and delete then we can define one metric called `container_actions` and use labels to specify the type of action. - - -```go -containerActions = ns.NewLabeledTimer("container_actions", "The number of milliseconds it takes to process each container action", "action") -``` - -The last parameter is the label name or key. -When adding a data point to the metric you will use the `WithValues` function to specify the `action` that you are collecting for. - -```go -containerActions.WithValues("create").UpdateSince(start) -``` - -4. Always use a unit - -The metric name should describe what you are measuring but you also need to provide the unit that it is being measured with. -For a timer, the standard unit is seconds and a counter's standard unit is a total. -For gauges you must provide the unit. -This package provides a standard set of units for use within the Docker projects. - -```go -Nanoseconds Unit = "nanoseconds" -Seconds Unit = "seconds" -Bytes Unit = "bytes" -Total Unit = "total" -``` - -If you need to use a unit but it is not defined in the package please open a PR to add it but first try to see if one of the already created units will work for your metric, i.e. seconds or nanoseconds vs adding milliseconds. - -## Docs - -Package documentation can be found [here](https://godoc.org/github.com/docker/go-metrics). - -## HTTP Metrics - -To instrument a http handler, you can wrap the code like this: - -```go -namespace := metrics.NewNamespace("docker_distribution", "http", metrics.Labels{"handler": "your_http_handler_name"}) -httpMetrics := namespace.NewDefaultHttpMetrics() -metrics.Register(namespace) -instrumentedHandler = metrics.InstrumentHandler(httpMetrics, unInstrumentedHandler) -``` -Note: The `handler` label must be provided when a new namespace is created. - -## Additional Metrics - -Additional metrics are also defined here that are not available in the prometheus client. -If you need a custom metrics and it is generic enough to be used by multiple projects, define it here. - - -## Copyright and license - -Copyright © 2016 Docker, Inc.

The nil pointer exception is not strictly necessary -// but mimics a similar, necessary exception in the behavior of -// UnmarshalJSON. -// -// Otherwise, Marshal uses the following type-dependent default encodings: -// -// Boolean values encode as JSON booleans. -// -// Floating point, integer, and Number values encode as JSON numbers. -// -// String values encode as JSON strings coerced to valid UTF-8, -// replacing invalid bytes with the Unicode replacement rune. -// The angle brackets "<" and ">" are escaped to "\u003c" and "\u003e" -// to keep some browsers from misinterpreting JSON output as HTML. -// Ampersand "&" is also escaped to "\u0026" for the same reason. -// -// Array and slice values encode as JSON arrays, except that -// []byte encodes as a base64-encoded string, and a nil slice -// encodes as the null JSON object. -// -// Struct values encode as JSON objects. Each exported struct field -// becomes a member of the object unless -// - the field's tag is "-", or -// - the field is empty and its tag specifies the "omitempty" option. -// The empty values are false, 0, any -// nil pointer or interface value, and any array, slice, map, or string of -// length zero. The object's default key string is the struct field name -// but can be specified in the struct field's tag value. The "json" key in -// the struct field's tag value is the key name, followed by an optional comma -// and options. Examples: -// -// // Field is ignored by this package. -// Field int `json:"-"` -// -// // Field appears in JSON as key "myName". -// Field int `json:"myName"` -// -// // Field appears in JSON as key "myName" and -// // the field is omitted from the object if its value is empty, -// // as defined above. -// Field int `json:"myName,omitempty"` -// -// // Field appears in JSON as key "Field" (the default), but -// // the field is skipped if empty. -// // Note the leading comma. -// Field int `json:",omitempty"` -// -// The "string" option signals that a field is stored as JSON inside a -// JSON-encoded string. It applies only to fields of string, floating point, -// integer, or boolean types. This extra level of encoding is sometimes used -// when communicating with JavaScript programs: -// -// Int64String int64 `json:",string"` -// -// The key name will be used if it's a non-empty string consisting of -// only Unicode letters, digits, dollar signs, percent signs, hyphens, -// underscores and slashes. -// -// Anonymous struct fields are usually marshaled as if their inner exported fields -// were fields in the outer struct, subject to the usual Go visibility rules amended -// as described in the next paragraph. -// An anonymous struct field with a name given in its JSON tag is treated as -// having that name, rather than being anonymous. -// An anonymous struct field of interface type is treated the same as having -// that type as its name, rather than being anonymous. -// -// The Go visibility rules for struct fields are amended for JSON when -// deciding which field to marshal or unmarshal. If there are -// multiple fields at the same level, and that level is the least -// nested (and would therefore be the nesting level selected by the -// usual Go rules), the following extra rules apply: -// -// 1) Of those fields, if any are JSON-tagged, only tagged fields are considered, -// even if there are multiple untagged fields that would otherwise conflict. -// 2) If there is exactly one field (tagged or not according to the first rule), that is selected. -// 3) Otherwise there are multiple fields, and all are ignored; no error occurs. -// -// Handling of anonymous struct fields is new in Go 1.1. -// Prior to Go 1.1, anonymous struct fields were ignored. To force ignoring of -// an anonymous struct field in both current and earlier versions, give the field -// a JSON tag of "-". -// -// Map values encode as JSON objects. -// The map's key type must be string; the map keys are used as JSON object -// keys, subject to the UTF-8 coercion described for string values above. -// -// Pointer values encode as the value pointed to. -// A nil pointer encodes as the null JSON object. -// -// Interface values encode as the value contained in the interface. -// A nil interface value encodes as the null JSON object. -// -// Channel, complex, and function values cannot be encoded in JSON. -// Attempting to encode such a value causes Marshal to return -// an UnsupportedTypeError. -// -// JSON cannot represent cyclic data structures and Marshal does not -// handle them.
