Struct WebGpuMemoryManager 

pub struct WebGpuMemoryManager { /* private fields */ }

Manages a pool of device-resident wgpu::Buffer objects, returning opaque u64 handles to callers.

All public methods are &self to allow shared references from the backend.

Implementations

impl WebGpuMemoryManager

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

Create a new memory manager backed by device.

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

Allocate a new device buffer of bytes bytes.

Returns an opaque handle that identifies the buffer.

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

Release the buffer associated with handle.

The handle is silently ignored if it is unknown (already freed).

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

Upload src (host bytes) into the device buffer identified by handle.

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

Download the device buffer identified by handle into dst (host bytes).

Uses a temporary MAP_READ staging buffer and blocks until the GPU work completes.

Trait Implementations

impl Debug for WebGpuMemoryManager

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

Formats the value using the given formatter.
