Change Log

for Rust Industrial I/O

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

iio_info_rs utility now supports network and URI contexts.
PR #19 macOS build makes a distinction for Intel and non-Intel builds when searching for Homebrew Frameworks (libiio library).
PR #20 Fix some clippy suggestions. Particularly cleaner casting of raw pointers, etc.

Started loosening thread safety restrictions:
- The Context is now Send and Sync. Internally it has canverted to using an Arc instead of an Rc to track it's internal data.
- The Device is now Send.
- For high performance with multiple device, though, it's still recommended to used fully-cloned contexts for each device
- For now, Channel and Buffer objects are still !Send and !Sync. So they should live in the same thread as their channel.
New functions to manipulate Context and InnerContext objects:
- Context::try_release_inner() attempts to get the inner context out of the context wrapper.
- Context::try_deep_clone() to make a new context around a deep copy of the inner context (and thus a copy of the C lib context).
- From<InnerContext> for Context

#12 Context construction now takes a Backend enumeration type.
The InnerContext is now public and can be cloned and sent to another thread to create a cloned context in the other thread.
#15 Generic attr_read() and attr_write() functions for devices, channels, and buffers.
#17 macOS support (for network clients)
Buffer attribute read/write functions and iterators moved into the Buffer struct.
Buffer struct now contains a clone of the Device from which it was created.
Device and Channel now support Clone trait.
Updates to the examples for more/different hardware.
New Version struct which is returned by the library and Context version query functions.

Support for libiio v0.21
Updated error handling:
- Support for std::error
- Implementation changed to use thiserror (from error_chain)
- Specific types defined for common errors intead of just string descriptions (WrongDataType, BadReturnSize, InvalidIndex, etc)
New device capabilities:
- remove_trigger()
- is_buffer_capable()
New utility app: riio_stop_all

Support for libiio v0.18
Further implementation of libiio functions for contexts, devices, channels, etc.
Functions to read and write buffers, with and without conversions, and to convert individual samples to and from hardware format.
[Breaking] Removed previous ChannelType for Input/Output as it conflicted with the library's channel types of Voltage, Current, Power, etc, and implemented the library type.
Contexts have a ref-counted "inner" representation using Rc<>, and can be "cloned" quickly by incrementing the count. (Thanks, @skrap!)
Devices carry a cloned reference to the context that created them, thus keeping the context alive until the last device using it gets dropped.
Some clippy-recommended lints.
Example app to collect and process data a buffer at a time, with conversions.
