Documentation

A Rust wrapper for libevdev

# Cargo.toml
[dependencies]
evdev-rs = "0.6.1"

to enable serialization support, enable the feature "serde"

# Cargo.toml
[dependencies]
evdev-rs = { version = "0.6.1", features = ["serde"] }

With a newer libevdev version (>= 1.10) enable the feature `libevdev-1-10` to
allow disabling a property. It also extends the `Enable` trait to `InputProp`,
enabling the use of `enable()`, `disable()` and `has()` for `InputProp` as well.

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 is an implementation of libevdev in Rust which provides most of the same features.

evdev-rs crate closely follows libevdev and hence enjoys all the complex handling that libevdev does. Some of the things that libevdev handles transparently, which may or may not be in evdev crate:

• handling of fake multitouch devices
• synching of slots and per-slot state
• transparent generation of missing tracking ids after SYN_DROPPED
• various boundary checks with defined error codes if you request invalid data (e.g. event codes that don't exist on the device)
• fd swapping on the same context
• disabling/enabling events on a per-context basis, so you can disable/enable ABS_FOO and then not care about quirks in the client-side code.
