Collection of windows with their associated renderers.

Implementations

impl<R> Windows<R>

pub fn new() -> Self

Creates an empty window collection.

pub fn insert(&mut self, window_data: WindowData, renderer: R) -> WindowId

Inserts a window and its renderer. Returns the WindowId.

pub fn remove(&mut self, id: &WindowId) -> Option<(WindowData, R)>

Removes a window by ID, returning its data and renderer if present.

pub fn get(&self, id: &WindowId) -> Option<&(WindowData, R)>

Returns a reference to the window data and renderer for the given ID.

pub fn get_mut(&mut self, id: &WindowId) -> Option<&mut (WindowData, R)>

Returns a mutable reference to the window data and renderer for the given ID.

pub fn is_empty(&self) -> bool

Returns true if there are no windows.

pub fn len(&self) -> usize

Returns the number of windows.

pub fn iter(&self) -> impl Iterator<Item = (&WindowId, &(WindowData, R))>

Iterates over all windows.

pub fn iter_mut( &mut self, ) -> impl Iterator<Item = (&WindowId, &mut (WindowData, R))>

Iterates mutably over all windows.

fn default() -> Self

Returns the “default value” for a type.
