Struct PingPongBuffer 

pub struct PingPongBuffer { /* private fields */ }

A double-buffer pair for iterative compute patterns (ping-pong).

Common in FDTD simulation, iterative blur, fluid simulation, and any algorithm that reads from one buffer and writes to another, then swaps.

Examples

use mabda::compute::PingPongBuffer;

let mut pp = PingPongBuffer::new(&device, &initial_data, "simulation");
for _ in 0..100 {
    pipeline.dispatch_with(pp.read(), pp.write(), workgroups);
    pp.swap();
}

Implementations

impl PingPongBuffer

pub fn new(device: &Device, size: u64, label: &str) -> Self

Create a ping-pong buffer pair, each with size bytes.

pub fn source(&self) -> &Buffer

The buffer to read from (current source).

pub fn dest(&self) -> &Buffer

The buffer to write to (current destination).

pub fn swap(&mut self)

Swap source and destination buffers.

pub fn index(&self) -> usize

Current iteration index (0 or 1).
