Struct Evdev 

pub struct Evdev { /* private fields */ }

The evdev pads on this machine, and their connection state.

Implementations

impl Evdev

pub fn new() -> Self

Pads under /dev/input, none of them found yet: the first poll scans.

pub fn poll(&mut self, emit: impl FnMut(GamepadEvent)) -> Result<(), EvdevError>

Reads every open pad and calls emit with what changed: connections, disconnections, and snapshots that differ from the last one reported. Open pads are read on every call; /dev/input is re-scanned for new ones only once RESCAN_INTERVAL has passed since the last scan.

Errors

An EvdevError for the last thing that went wrong unexpectedly; see its variants. Everything else was still polled.
