0.6.1

Magnus 0.6.1 is a patch release, with 1 change.

This release adds support for rb-sys' stable-api feature.

Thanks to @​gmalette for this change.

0.6.0

Magnus 0.6.0 makes some breaking API changes to improve thread safety. A handful of fixes and new features are also included.

Magnus is a Rust library providing a high-level easy-to-use interface to the C API of the Ruby programming language. Magnus lets you write Ruby extension libraries (or 'gems') in Rust, or embed Ruby in your Rust program.

Thread Safety

Previous versions of Magnus have ignored thread safety in aid of getting something working, but support for threads and running Rust code outside of the Global VM Lock via rb_thread_call_without_gvl have been common feature requests. This release prepares for the introduction of those features with some breaking API changes.

To this end all APIs that create Ruby objects have been moved to a new Ruby handle which can only be obtained on a Ruby thread. For example RArray::new() becomes Ruby::ary_new(&self) (currently RArray::new() still exists as a wrapper around Ruby::get().unwrap().ary_new()). Default implementations have been removed. Additionally Ruby types are no longer Send & Sync. An Opaque wrapper type can be used to pass Ruby types between threads where they can only be unwrapped on a Ruby thread.

To make getting ahold of the Ruby handle simple, functions bound as Ruby methods with method!() and function!(), along with the function marked with #[magnus::init] optionally take &Ruby as a first argument.

Other API Changes

The minimum supported Rust version is now 1.61.

The bytes-crate and rb-sys-interop features have been renamed to bytes and rb-sys respectively.

Previously all Ruby types, such as RString, RArray, etc Deref'd to Value, allowing Value methods to be called on all Ruby types. This is no longer the case. All Value methods have been moved to the ReprValue trait, which is implemented by Value and all other Ruby types.

This allows typed_data::Obj<T> to Deref to T, turning typed_data::Obj into a 'smart pointer' type that makes advanced use of wrapped data much more pleasant.

New Features

• rb_assert!() macro
• value::Lazy lazily initialises a Ruby value so it can be assigned to a static
• Support for subclassable wrapped Rust data via Class::define_alloc_func‎ and Ruby::obj_wrap_as
• The kwargs!() macro and KwArgs type can be used to pass keyword arguments to ReprValue::funcall, et al.
• Documentation examples for almost every function

Upgrading

If you encounter a lot of deprecation warnings when upgrading it may be easier to ignore warnings to concentrate on fixing errors, assuming your project is setup with a Rake and a 'compile' task this can be done with:

RUSTFLAGS=-Awarnings rake compile

It is also possible to ignore errors due to Value no longer being Send + Sync by activating the deprecated-send-sync-value feature:

magnus = { version = "0.6", features = ["deprecated-send-sync-value"] }

This feature is intended purely as a convenience when upgrading and will be removed with the next release.

Changelog

Sourced from magnus's changelog.

[0.6.1] - 2023-08-20

Changed

• Support rb-sys' stable-api feature.

[0.5.5] - 2023-08-20

Changed

• Support rb-sys' stable-api feature.
• Minimum supported Rust version is 1.60.
• Ruby 2.6 support requires enabling rb-sys' stable-api-compiled-fallback feature in your Cargo.toml like so: rb-sys = { version = "*", default-features = false, features = ["stable-api-compiled-fallback"] }

[0.6.0] - 2023-07-28

Added

• value::Opaque can be used to wrap a Ruby type to make it Send + Sync.
• value::Lazy lazily initialises a Ruby value so it can be assigned to a static.
• value::OpaqueId is a Send + Sync version of value::Id.
• value::LazyId is an Id with a const constructor so can be assigned to a static and derefs to OpaqueId.
• error::OpaqueError is a Send + Sync version of Error.
• The #[magnus(opaque_attr_reader)] attribute can be set on Opaque wrapped fields of a struct when deriving TypedData to generate a method to return the inner value.
• Ruby::init function to initialise Ruby when embedding Ruby in Rust that runs a function with Ruby initialised, passing &Ruby.
• rb_assert!() macro to assert a Ruby expression evaluates to a truthy value.
• Class::undef_default_alloc_func to remove a class' allocator function only if it is Ruby's default allocator function.
• Class::obj_alloc and Class::define_alloc_func for allocating an object without calling initialize, and for defining an allocator function.
• RTypedData::wrap_as & typed_data::Obj<T>::wrap_as can be used to dynamically set the class when wrapping Rust data in a Ruby object. This can be used to allow wrapped data to be subclassed in Ruby.
• Exception::exception_class returns the class of an exception as an ExceptionClass.
• The kwargs!() macro and KwArgs type can be used to pass keyword arguments to ReprValue::funcall, et al.

Changed

• Minimum supported Rust version in now 1.61.
• The bytes-crate feature has been renamed to bytes.
• The rb-sys-interop feature has been renamed to rb-sys.
• Ruby types are no longer Send or Sync. These types can be made Send & Sync with the deprecated-send-sync-value feature. This feature is meant to ease upgrading and will be removed with the next release.
• Value's methods moved to the ReprValue trait.
• typed_data::Obj<T> derefs to T so now T's methods can be called directly on typed_data::Obj<T>.
• ReprValue and TryConvert added to magnus::prelude.
