Struct WasmMemoryManager 

pub struct WasmMemoryManager { /* private fields */ }

Browser-side buffer manager that uses async map_async staging.

This mirrors WebGpuMemoryManager but is designed to work within the single-threaded browser event loop where blocking calls are not allowed.

Implementations

impl WasmMemoryManager

pub fn new(device: Arc<WasmGpuDevice>) -> Self

Create a new WASM memory manager backed by device.

pub fn alloc(&self, bytes: usize) -> WebGpuResult<u64>

Allocate a device buffer of bytes bytes.

pub fn free(&self, handle: u64) -> WebGpuResult<()>

Free the buffer identified by handle.

pub fn copy_htod(&self, handle: u64, src: &[u8]) -> WebGpuResult<()>

Upload host bytes to the device buffer (host-to-device copy).

Uses Queue::write_buffer which is available in both native and WASM.

pub fn copy_dtoh(&self, dst: &mut [u8], handle: u64) -> WebGpuResult<()>

Download device buffer to host bytes (device-to-host copy).

Uses a staging buffer with map_async and blocks via pollster::block_on. On native WASM, callers should prefer the async variant or schedule this on a web worker to avoid blocking the main thread.

Trait Implementations

impl Debug for WasmMemoryManager

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
