Struct show_image::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() -> WindowId

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

pub fn clone(&self) -> WindowId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WindowId

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

Formats the value using the given formatter.

impl Hash for WindowId

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

Feeds this value into the given Hasher.

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

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

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

Compares and returns the minimum of two values.

#[must_use]

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

Restrict a value to a certain interval.

impl PartialEq<WindowId> for WindowId

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

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

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

This method tests for !=.

impl PartialOrd<WindowId> for WindowId

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

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

#[must_use]

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

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

#[must_use]

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]

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

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

#[must_use]

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

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