[−][src]Trait azul_webrender::AsyncPropertySampler

pub trait AsyncPropertySampler {
    fn register(&self);
    fn sample(
        &self, 
        document_id: DocumentId, 
        doc: &FastHashMap<PipelineId, Epoch>
    ) -> 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, document_id: DocumentId, doc: &FastHashMap<PipelineId, Epoch> ) -> 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.
