Struct ManagedBuffer 

pub struct ManagedBuffer { /* private fields */ }

RAII wrapper for automatic buffer deallocation

Implementations

impl ManagedBuffer

pub fn new(buffer: GpuBuffer, pool: Arc<MemoryPool>) -> Self

Create a new managed buffer

pub fn buffer(&self) -> &GpuBuffer

Get a reference to the buffer.

Panics

Panics if the buffer has already been released via ManagedBuffer::take. Under normal usage this cannot happen because take() consumes self.

pub fn try_buffer(&self) -> Result<&GpuBuffer>

Fallible variant of ManagedBuffer::buffer.

Errors

Returns GpuError::Internal if the buffer has already been released.

pub fn take(self) -> Result<GpuBuffer>

Take ownership of the buffer, preventing automatic deallocation.

Errors

Returns GpuError::Internal if the buffer has already been released.

Methods from Deref<Target = GpuBuffer>

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.

Trait Implementations

impl Deref for ManagedBuffer

type Target = GpuBuffer

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Drop for ManagedBuffer

fn drop(&mut self)

Executes the destructor for this type.
