pub async fn new<W: HasRawDisplayHandle + HasRawWindowHandle>( window: &W, surface_size: Dimension ) -> Result<Self, Error>

Attempts to create a WindowHandle for the provided window.

The provided size should be the current size of the window’s surface.

pub fn wgpu_surface(&self) -> &Surface

Returns the wgpu::Surface this WindowHandle uses.

pub fn resize_surface(&mut self, new_size: Dimension)

Resizes the surface of this WindowHandle.

Should be called when the window’s manager emits a resize event. Does nothing if the new size is zero.

pub fn frame(&self) -> Result<Frame<'_, Self>, Error>

Creates a Frame that can be used to draw to the window.
