The renderer is responsible for submitting to the GPU the work prepared by the RenderBackend.


Optional trait object that allows the client application to provide external buffers for image data.

Optional trait object that allows the client application to provide a texture handle to copy the WR output to.

List of profile results from previous frames. Can be retrieved via get_frame_profiles().


impl Renderer

Initializes webrender and creates a Renderer and RenderApiSender.


Initializes a Renderer with some reasonable values. For more information see RendererOptions.

This example is not tested
let opts = webrender::RendererOptions {
   device_pixel_ratio: 1.0,
   resource_override_path: None,
   enable_aa: false,
let (renderer, sender) = Renderer::new(opts);

Returns the Epoch of the current frame in a pipeline.

Processes the result queue.

Should be called before render(), as texture cache updates are done here.

Set a callback for handling external images.

Set a callback for handling external outputs.

Retrieve (and clear) the current list of recorded frame profiles.

Returns true if the active rendered documents (that need depth buffer) intersect on the main framebuffer, in which case we don't clear the whole depth and instead clear each document area separately.

Renders the current frame.

A Frame is supplied by calling [generate_frame()][genframe]. [genframe]: ../../webrender_api/struct.DocumentApi.html#method.generate_frame

Pass-through to Device::read_pixels_into, used by Gecko's WR bindings.
