Trait webrender::AsyncPropertySampler

pub trait AsyncPropertySampler {
    fn register(&self);
    fn sample(&self) -> Vec<FrameMsg>;
    fn deregister(&self);
}

Allows callers to hook into the main render_backend loop and provide additional frame ops for generate_frame transactions. These functions are all called from the render backend thread.

Required Methods

fn register(&self)

This is called exactly once, when the render backend thread is started and before it processes anything.

fn sample(&self) -> Vec<FrameMsg>

This is called for each transaction with the generate_frame flag set (i.e. that will trigger a render). The list of frame messages returned are processed as though they were part of the original transaction.

fn deregister(&self)

This is called exactly once, when the render backend thread is about to terminate.
