Enum ChunkItem 

pub enum ChunkItem<'b, S: Sample, const N: usize> {
    Full {
        ch: usize,
        sample: usize,
        inp: &'b [S; N],
        out: &'b mut [S; N],
    },
    Tail {
        ch: usize,
        sample: usize,
        inp: &'b [S],
        out: &'b mut [S],
    },
}

One yielded chunk from AudioBuffer::chunks_mut.

Full is the SIMD-friendly path: inp and out are stack arrays of exactly N elements, ready to feed truce-simd’s block ops. Tail is the trailing fragment when num_samples() isn’t a multiple of N; fall back to a scalar loop.

Variants

Full

Full N-sample chunk. The &[S; N] / &mut [S; N] are the shape truce-simd ops are written against - no slice length check at the call site.

Fields

ch: usize

Channel index this chunk belongs to.

sample: usize

Sample offset within the audio block this chunk starts at. Use this when indexing into a precomputed envelope array - chunks_mut iterates channel-major, so the envelope (typically read once per audio block via read_block::<num_samples>()) is shared across all channel passes.

inp: &'b [S; N]

Read-only N-sample input slice.

out: &'b mut [S; N]

Mutable N-sample output slice.

Tail

Trailing chunk when num_samples() isn’t a multiple of N. Length is in (0, N). Fall back to scalar processing.

Fields

ch: usize

Channel index this chunk belongs to.

sample: usize

Sample offset within the audio block this chunk starts at.

inp: &'b [S]

Read-only tail input slice; length < N.

out: &'b mut [S]

Mutable tail output slice; length < N.
