DeviceId

Struct DeviceId

pub struct DeviceId(/* private fields */);

Expand description

Identifier of an input device.

Whenever you receive an event arising from a particular input device, this event contains a DeviceId which identifies its origin. Note that devices may be virtual (representing an on-screen cursor and keyboard focus) or physical. Virtual devices typically aggregate inputs from multiple physical devices.

Implementations§

impl DeviceId

pub const fn into_raw(self) -> i64

Convert the DeviceId into the underlying integer.

This is useful if you need to pass the ID across an FFI boundary, or store it in an atomic.

pub const fn from_raw(id: i64) -> DeviceId

Construct a DeviceId from the underlying integer.

This should only be called with integers returned from DeviceId::into_raw.
