Struct DeviceId 

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

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) -> Self

Construct a DeviceId from the underlying integer.

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

Trait Implementations

impl Clone for DeviceId

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Ord for DeviceId

fn cmp(&self, other: &Self) -> 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, 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: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for DeviceId

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

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
