Trait AudioWorkerSource 

pub trait AudioWorkerSource: Send + 'static {
    type Chunk: Send + 'static;

    // Required methods
    fn step_track(&mut self) -> TrackStep<Self::Chunk>;
    fn timeline(&self) -> &Timeline;
}

Trait for audio sources processed in a blocking worker thread.

The worker calls step_track() once per scheduling round. Each call performs at most one FSM transition and returns a [TrackStep] that tells the worker what happened.

Required Associated Types

type Chunk: Send + 'static

Required Methods

fn step_track(&mut self) -> TrackStep<Self::Chunk>

Advance the track FSM by one step.

Handles seek preemption, source readiness, decoding, and all internal state transitions. Returns:

• Produced — decoded chunk ready for the consumer.
• StateChanged — internal transition; caller should call again.
• Blocked — the source is not ready; the caller should wait for a wake.
• Eof — end of stream (may transition out via seek-after-EOF).
• Failed — terminal failure.

fn timeline(&self) -> &Timeline

Access the shared timeline for epoch queries.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
