Struct glutin::event::DeviceId

pub struct DeviceId(_);

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() -> DeviceId

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

pub fn clone(&self) -> DeviceId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for DeviceId

impl Debug for DeviceId

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

Formats the value using the given formatter.

impl Eq for DeviceId

impl Hash for DeviceId

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl Ord for DeviceId

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

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

Compares and returns the minimum of two values.

#[must_use]

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

Restrict a value to a certain interval.

impl PartialEq<DeviceId> for DeviceId

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<DeviceId> for DeviceId

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

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

#[must_use]

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

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

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

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

#[must_use]

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

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]

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

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