Safe wrapper around Rust FFI bindings for libgpiod

libgpiod 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
