Struct ProcessBlock 

pub struct ProcessBlock<'a> {
    pub frames: u32,
    pub in_audio: &'a [&'a [f32]],
    pub out_audio: &'a mut [&'a mut [f32]],
    pub in_events: &'a [BlockEvent<'a>],
    pub out_events: &'a mut dyn EventSink,
    pub transport: Transport,
    pub scratch: &'a mut BlockArena,
}

One processing block handed to a Processor: input and output audio lanes, event streams, transport state, and a scratch arena.

Fields

frames: u32

Number of valid frames in each audio lane for this block.

in_audio: &'a [&'a [f32]]

Input audio lanes, one slice per input channel.

out_audio: &'a mut [&'a mut [f32]]

Output audio lanes, one mutable slice per output channel.

in_events: &'a [BlockEvent<'a>]

Input events delivered to the processor for this block.

out_events: &'a mut dyn EventSink

Sink the processor pushes outgoing events into.

transport: Transport

Transport state (playhead, tempo, play flag) for this block.

scratch: &'a mut BlockArena

Per-block scratch allocator for temporary buffers.

Implementations

impl ProcessBlock<'_>

pub fn validate_audio_lanes(&self) -> Result<()>

Validates that every input and output audio lane holds at least frames samples.
