Struct BeginFrameReturn 

pub struct BeginFrameReturn { /* private fields */ }

Available on crate features experimental and HeadlessExperimental and Page and Runtime only.

Sends a BeginFrame to the target and returns when the frame was completed. Optionally captures a screenshot from the resulting frame. Requires that the target was created with enabled BeginFrameControl. Designed for use with –run-all-compositor-stages-before-draw, see also https://goo.gl/3zHXhB for more background.
