Struct GpuBuffer 

pub struct GpuBuffer { /* private fields */ }

GPU buffer wrapper with automatic memory management

Implementations

impl GpuBuffer

pub fn new( device: &GpuDevice, size: u64, buffer_type: BufferType, ) -> Result<Self>

Create a new GPU buffer

Arguments

• device - GPU device
• size - Buffer size in bytes
• buffer_type - Type of buffer to create

Errors

Returns an error if buffer creation fails.

pub fn with_data( device: &GpuDevice, data: &[u8], buffer_type: BufferType, ) -> Result<Self>

Create a buffer initialized with data

Arguments

• device - GPU device
• data - Initial data
• buffer_type - Type of buffer to create

Errors

Returns an error if buffer creation fails.

pub fn write(&self, queue: &Queue, offset: u64, data: &[u8]) -> Result<()>

Write data to the buffer

Arguments

• queue - GPU queue for data transfer
• offset - Offset in bytes
• data - Data to write

Errors

Returns an error if the write operation fails or if offset + data size exceeds buffer size.

pub async fn read_async( &self, _device: &GpuDevice, offset: u64, size: u64, ) -> Result<Vec<u8>>

Read data from the buffer (asynchronously)

Arguments

• device - GPU device
• offset - Offset in bytes
• size - Number of bytes to read

Errors

Returns an error if the buffer type doesn’t support reading or if the read operation fails.

pub fn read( &self, device: &GpuDevice, offset: u64, size: u64, ) -> Result<Vec<u8>>

Read data from the buffer (blocking)

Arguments

• device - GPU device
• offset - Offset in bytes
• size - Number of bytes to read

Errors

Returns an error if the buffer type doesn’t support reading or if the read operation fails.

pub fn buffer(&self) -> &Buffer

Get the underlying WGPU buffer

pub fn size(&self) -> u64

Get buffer size in bytes

pub fn buffer_type(&self) -> BufferType

Get buffer type

pub fn copy_to( &self, encoder: &mut CommandEncoder, dst: &Self, src_offset: u64, dst_offset: u64, size: u64, ) -> Result<()>

Copy data from this buffer to another buffer

Arguments

• encoder - Command encoder for recording the copy operation
• dst - Destination buffer
• src_offset - Source offset in bytes
• dst_offset - Destination offset in bytes
• size - Number of bytes to copy

Errors

Returns an error if offsets or size are invalid.
