# Safe wrapper around Rust FFI bindings for libgpiod [libgpiod](https://git.kernel.org/pub/scm/libs/libgpiod/libgpiod.git/tree/README) is a C library that provides an easy to use abstraction over the Linux GPIO character driver. This crate builds on top of `libgpiod-sys` and exports a safe interface to the C library. ## Build requirements By default, `libgpiod-sys` builds against the libgpiod version identified via `pkg-config`. See the `README.md` of `libgpiod-sys` for options to override that. Currently at least libgpiod 2.0 is required with the default feature set. ## Features The Rust bindings will usually be built against whatever libgpiod version a system provides. Hence, only the functionality of the oldest supported libgpiod C library will be exposed by default. Setting flags allows to increase the base version and export features of newer versions: - `v2_1`: Minimum version of `2.1.x` - `vnext`: The upcoming, still unreleased version of the C lib ## License This project is licensed under either of - [Apache License](http://www.apache.org/licenses/LICENSE-2.0), Version 2.0 - [BSD-3-Clause License](https://opensource.org/licenses/BSD-3-Clause)
