}

Implementations

impl Renderer

pub fn offscreen(width: u32, height: u32) -> Result<Self, String>

Draw into an offscreen Rgba8Unorm texture (the pixel host, tests).

pub unsafe fn on_window( display: RawDisplayHandle, window: RawWindowHandle, width: u32, height: u32, ) -> Result<Self, String>

Present to a native window.

Safety

The handles must be valid and outlive the renderer.

pub fn resize(&mut self, width: u32, height: u32)

pub fn evict(&mut self, key: u64)

Drop a cached glyph or image upload.

pub fn read_pixels(&self) -> Option<Vec<u32>>

The offscreen pixels as 0x00RRGGBB (None on a window).

pub fn max_texture(&self) -> u32

pub unsafe fn draw(&mut self, frame: &MouserFrame) -> c_int

Draw (and present on a window). DRAW_AGAIN when the surface was reset.

Safety

The frame’s pointers must be valid for the call.
