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 unsafe fn dummy() -> Self

Returns a dummy DeviceId, useful for unit testing. 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.

Passing this into a winit function will result in undefined behavior.

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 Debug for DeviceId

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for DeviceId

impl Hash for DeviceId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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>

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.
