Enum GenerateFrame 

pub enum GenerateFrame {
    Yes {
        id: u64,
        present: bool,
        tracked: bool,
    },
    No,
}

Whether to generate a frame, and if so, an id that allows tracking this transaction through the various frame stages.

Variants

Generate a frame if something changed.

Fields

id: u64

An id that allows tracking the frame transaction through the various frame stages. Specified by the caller of generate_frame().

present: bool

If false, (a subset of) the frame will be rendered, but nothing will be presented on the window.

tracked: bool

This flag is used by Firefox to differentiate between frames that participate or not in the frame throttling mechanism.

No

Don’t generate a frame even if something has changed.
