Struct winit::window::WindowId

pub struct WindowId(_);

Identifier of a window. Unique for each window.

Can be obtained with window.id().

Whenever you receive an event specific to a window, this event contains a WindowId which you can then compare to the ids of your windows.

Implementations

impl WindowId

pub unsafe fn dummy() -> Self

Returns a dummy WindowId, 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 WindowId.

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

Trait Implementations

impl Clone for WindowId

fn clone(&self) -> WindowId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for WindowId

impl Debug for WindowId

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

Formats the value using the given formatter.

impl Eq for WindowId

impl Hash for WindowId

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

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 WindowId

fn cmp(&self, other: &WindowId) -> 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<WindowId> for WindowId

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

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

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

This method tests for !=.

impl PartialOrd<WindowId> for WindowId

fn partial_cmp(&self, other: &WindowId) -> 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.
