Struct Playback 

pub struct Playback { /* private fields */ }

A record playing, one frame at a time: on an App made from the game’s Start (prepare), on a platform from HeadlessPlatform::from_session. It needs no Harness, so a running build can replay a record too.

Implementations

impl Playback

pub fn new(record: &SessionRecord) -> Self

The playback of record, from its first frame.

pub fn next<G: GameData>( &mut self, app: &mut App<G>, platform: &mut HeadlessPlatform, ) -> Option<Result<u32, FrameDifference>>

Plays the next frame at its recorded time, and answers its number, or how its hash differs; a frame with no hash has the last one written. None once the record is played: from its last frame on, platform’s music and keyboard are its own again.

pub fn is_done(&self) -> bool

Whether every frame has played.

pub fn now(&self) -> Millis

The time of the last frame played, for a driver that goes on from the record’s end; before the first, the record’s start.

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Playback
