pub fn time_frames<A: ResourceApp>(
scenario: Option<&str>,
frames: usize,
) -> Result<Vec<Duration>, String>Expand description
How long each of frames frames of A’s capture of scenario takes to
sync, lay out and draw, after one frame that warms the text caches: what
a --bench command reports. Where no native runner is linked (a browser
page) there is no headless capture to time.
