[#55](https://github.com/rust-embedded/gpio-cdev/pull/55). +- Fix lsgpio example to output gpio line flags. +- Add `is_empty()` function for `Lines` struct. +- Add common trait implementations for public structures. +- Breaking change of `LineEventHandle::get_event()` which now expects `&mut self`. +- MSRV is now 1.46.0. +- Updated `nix` to version `0.22`. +- Updated `quicli` to version `0.4`. +- Updated `bitflags` to version `1.3`. + + +## [v0.4.0] - 2020-08-01 + +- Removed pub "errors" module. Error now exposed at top level. +- MSRV is now 1.39.0 +- Add support behind a feature flag for reading events from a line as a Stream via tokio. [#35](https://github.com/rust-embedded/gpio-cdev/pull/35). + +## [v0.3.0] - 2020-02-10 + +Refactored Errors: +- Removed the `error-chain` dependency. +- Errors are now implemented "manually" with `ErrorKind` and `IoctlKind` enums. +- The encompassing `Error` type implements the `std::error::Error` trait. + +## v0.2.0 - 2018-12-12 + +Adds the ability to create a collection of lines from a single chip and read or write those lines simultaneously with a single stystem call. + +- A new `Lines` object (plural) was added. It is a collection of individual `Line` objects on a single `Chip` which can be read or written simultaneously with a single system call. +- A `Line` now just contains the reference to the Chip and the offset number. No system call is incurred when one is created. +- Information about an individual line is now represented by a separate `LineInfo` struct which can be obtained from the function `Line::info()`. This incurs a system call to retrieve the information. +- Creating a `Line` can't fail unless the caller specifies an offset that is out of range of the chip. +- The `LineIterator` can not fail since it checks the offset range. So now its item is just a `Line`, and not `Result<Line>`. +- There was no longer a need for `Line::refresh()` so it was removed. +- Since a `Line` object is trivial to create, it is now OK to have `Lines` be a simple collection of `Line` structs. + +## v0.1.0 - 2018-09-28 + +- Initial release of the library with basic operations centered around operating + on a single line at a time. + +[Unreleased]: https://github.com/rust-embedded/gpio-cdev/compare/0.6.0...HEAD +[v0.6.0]: https://github.com/rust-embedded/gpio-cdev/compare/0.5.1...0.6.0 +[v0.5.1]: https://github.com/rust-embedded/gpio-cdev/compare/0.5.0...0.5.1 +[v0.5.0]: https://github.com/rust-embedded/gpio-cdev/compare/0.4.0...0.5.0 +[v0.4.0]: https://github.com/rust-embedded/gpio-cdev/compare/0.3.0...0.4.0 |
