Bindings to libevdev for interacting with evdev devices. It moves the common tasks when dealing with evdev devices into a library and provides a library interface to the callers, thus avoiding erroneous ioctls, etc.

Build Status Latest Version Documentation

A Rust wrapper for libevdev

# Cargo.toml
[dependencies]
evdev-rs = "0.4.0"

to enable serialization support, enable the feature "serde"

# Cargo.toml
[dependencies]
evdev-rs-tokio = { version = "0.4.0", features = ["serde"] }

Why a libevdev wrapper?

The evdev protocol is simple, but quirky, with a couple of behaviors that are non-obvious. libevdev transparently handles some of those quirks.

The evdev crate on [1] is an implementation of evdev in Rust. Nothing wrong with that, but it will miss out on any more complex handling that libevdev provides.
