Enum Playback 

Source 
pub enum Playback {
    Paused,
    Playing {
        speed: PlaybackSpeed,
    },
}
Expand description

The replay playback state (docs/04-replay-mode.md §4): paused, or playing at a PlaybackSpeed. Playback stops at end_step and never wraps — that clamp lives in TimelineCursor::seek, so this type models the quantum and the play/pause transition only, not the tick timer (the tick cadence is the app’s, issue #34).

Variants§

§

Paused

Playback is paused (the default on load).

§

Playing

Playback is running at the given speed.

Fields

§speed: PlaybackSpeed

The active speed multiplier.

Implementations§

Source§

impl Playback

Source

pub const fn playing(speed: PlaybackSpeed) -> Self

Start playback at speed.

Source

pub const fn is_playing(self) -> bool

Whether playback is currently running.

Source

pub const fn speed(self) -> Option<PlaybackSpeed>

The active PlaybackSpeed, or None while paused.

Source

pub const fn toggled(self, resume_speed: PlaybackSpeed) -> Self

Toggle between paused and playing: pause when playing, or resume at resume_speed when paused. The pure state transition a play/pause key drives (issue #34 wires the key).

Source

pub const fn tick_seek(self) -> Option<SeekTo>

The SeekTo one scheduled playback tick applies to the cursor, or None while paused. Playing at ×N yields SeekTo::StepBy(N); the cursor clamps the result to end_step, so playback stops at the end of the tape and never wraps (docs/04-replay-mode.md §4). This is the quantum only — the tick cadence is the app’s (issue #34).
