Enum Pacing 

#[non_exhaustive]
pub enum Pacing {
    RealTime,
    Unpaced,
}

How SceneRunner::run paces frame delivery.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

RealTime

Deliver frames against the wall clock: sleep until a frame is due and drop one that is more than a frame period late. Playback.

Unpaced

Deliver every frame as soon as it is decoded: the clock is the runner’s own position, moved one frame period per presented frame, so nothing is ever late and nothing is dropped or slept for. For checks that must see each frame (tests, thumbnail strips). Reverse playback and the pause poll still wait on the wall clock.
