Struct winit::event::DeviceId

source ·
pub struct DeviceId(pub(crate) DeviceId);
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§

source§

impl DeviceId

source

pub const fn dummy() -> Self

Returns a dummy id, useful for unit testing.

§Notes

The only guarantee made about the return value of this function is that it will always be equal to itself and to future values returned by this function. No other guarantees are made. This may be equal to a real DeviceId.
