ScratchPool

sesh_sdk::scratch

Struct ScratchPool 

Source 
pub struct ScratchPool<const N: usize, const FRAMES: usize> { /* private fields */ }
Expand description

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

Const-constructed, zero-initialized in the data segment. Uses UnsafeCell for interior mutability — safe because WASM is single-threaded.

§Example

use sesh_sdk::Scratch;

static SCRATCH: Scratch = Scratch::new();

fn process(channels: &mut [&mut [f32]]) {
    let [mod_buf, tap_l, tap_r, out_l, out_r, ..] = SCRATCH.get();
    // use buffers...
}

Implementations§

Source§

impl<const N: usize, const FRAMES: usize> ScratchPool<N, FRAMES>

Source

pub const fn new() -> Self

Source

pub fn get(&self) -> &mut [[f32; FRAMES]; N]

Get mutable access to all buffers. Destructure into individual &mut [f32; FRAMES] references for non-overlapping borrows.
