Struct ScratchPool 

pub struct ScratchPool { /* private fields */ }

Heap-allocated buffer pool for intermediate results during audio processing.

Each call to buf(frames) returns the next available &mut [f32] of the requested length. The cursor wraps around when all slots are used.

Uses interior mutability so multiple buffers can be live simultaneously.

Example

use sesh_sdk::Scratch;

let scratch = Scratch::new();
let frames = 128;
let a = scratch.buf(frames);
let b = scratch.buf(frames);
let c = scratch.buf(frames);
// a, b, c are all valid simultaneously

Implementations

impl ScratchPool

pub fn with_capacity(n: usize, frames_cap: usize) -> Self

Create a new scratch pool with n buffers of frames_cap frames each.

pub fn new() -> Self

Create a default scratch pool: 128 buffers of 2048 frames (1MB).

pub fn buf(&self, frames: usize) -> &mut [f32]

Get the next scratch buffer, sliced to frames. Wraps when all slots are used.
