Struct DeviceId 

pub struct DeviceId(pub u32);

Input vocabulary, defined in crcbl_core::input and re-exported so a consumer of the event stream needs one use rather than two.

See the crate docs for why these live in crcbl-core. Which physical device an event came from.

The input design requires a per-device id on raw events from day one, because local-multiplayer device-to-player assignment is post-MVP but is impossible to retrofit into an event stream that never said which keyboard pressed the key. Ids are unique for the lifetime of the process and are not reused when a device is unplugged.

Implementations

impl DeviceId

pub const UNKNOWN: DeviceId

The device that events with no attributable source carry.

Backends that cannot tell two keyboards apart (X11 core protocol without XInput2, and the browser) use this for everything, and so do synthesized events from a replay or a test script.

Trait Implementations

impl Clone for DeviceId

fn clone(&self) -> DeviceId

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for DeviceId

impl Ord for DeviceId

fn cmp(&self, other: &DeviceId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for DeviceId

fn eq(&self, other: &DeviceId) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for DeviceId

fn partial_cmp(&self, other: &DeviceId) -> Option<Ordering>
