#![cfg_attr(feature = "unstable", feature(drain))]
//! Linux event device handling.
//!
//! The Linux kernel's "evdev" subsystem exposes input devices to userspace in a generic,
//! consistent way. I'll try to explain the device model as completely as possible. The upstream
//! kernel documentation is split across two files:
//!
//! - https://www.kernel.org/doc/Documentation/input/event-codes.txt
//! - https://www.kernel.org/doc/Documentation/input/multi-touch-protocol.txt
//!
//! # Device capabilities
//!
//! Devices can expose a few different kinds of events, specified by the `Types` bitflag. Each
//! event type (except for RELATIVE and SYNCHRONIZATION) also has some associated state. See the documentation for
//! `Types` on what each type corresponds to.
//!
//! This state can be queried. For
//! example, the `Device::leds_lit` method will tell you which LEDs are currentl lit on the input
//! device. This state is not automatically synchronized with the kernel. However, as the
//! application reads events, this state will be updated if it is older than the event.
//!
//!
//! As the state changes, the
//! kernel will write events into a ring buffer. The application can read from this ring buffer,
//! thus retreiving events. However, if the ring buffer becomes full, the kernel will *drop* every
//! event in the ring buffer and leave an event telling userspace that it did so. At this point, if
//! the application were using the events it received to update its internal idea of what state the
//! hardware device is in, it will be wrong: it is missing some events. This library tries to ease
//! that pain.
