Struct script::dom::document::FakeRequestAnimationFrameCallback

pub struct FakeRequestAnimationFrameCallback {
    document: Trusted<Document>,
}

A fake requestAnimationFrame() callback—“fake” because it is not triggered by the video refresh but rather a simple timer.

If the page is observed to be using requestAnimationFrame() for non-animation purposes (i.e. without mutating the DOM), then we fall back to simple timeouts to save energy over video refresh.

Fields

document: Trusted<Document>

The document.
