Struct GpuBuffer 

pub struct GpuBuffer<T: Pod> { /* private fields */ }

GPU buffer wrapper with type safety.

This struct wraps a WGPU buffer and provides type-safe operations for uploading and downloading data to/from the GPU.

Implementations

impl<T: Pod> GpuBuffer<T>

pub fn new( context: &GpuContext, len: usize, usage: BufferUsages, ) -> GpuResult<Self>

Create a new GPU buffer with the specified size and usage.

Errors

Returns an error if buffer creation fails or size is invalid.

pub fn from_data( context: &GpuContext, data: &[T], usage: BufferUsages, ) -> GpuResult<Self>

Create a GPU buffer from existing data.

Errors

Returns an error if buffer creation or upload fails.

pub fn staging(context: &GpuContext, len: usize) -> GpuResult<Self>

Create a staging buffer for CPU-GPU transfers.

Errors

Returns an error if buffer creation fails.

pub fn write(&mut self, data: &[T]) -> GpuResult<()>

Write data to the GPU buffer.

Errors

Returns an error if the buffer doesn’t support writes or data size doesn’t match buffer size.

pub async fn read(&self) -> GpuResult<Vec<T>>

Read data from the GPU buffer asynchronously.

Errors

Returns an error if the buffer doesn’t support reads or mapping fails.

pub fn read_blocking(&self) -> GpuResult<Vec<T>>

Read data from the GPU buffer synchronously (blocking).

Errors

Returns an error if the buffer doesn’t support reads or mapping fails.

pub fn copy_from(&mut self, source: &GpuBuffer<T>) -> GpuResult<()>

Copy data from another GPU buffer.

Errors

Returns an error if buffer sizes don’t match or copy is not supported.

pub fn len(&self) -> usize

Get the number of elements in the buffer.

pub fn is_empty(&self) -> bool

Check if the buffer is empty.

pub fn size_bytes(&self) -> u64

Get the buffer size in bytes.

pub fn buffer(&self) -> &Buffer

Get the underlying WGPU buffer.

pub fn usage(&self) -> BufferUsages

Get buffer usage flags.
