Struct PooledBuffer 

pub struct PooledBuffer<T: Copy> { /* private fields */ }

A device buffer allocated from a MemoryPool.

Unlike DeviceBuffer, a PooledBuffer is freed asynchronously — the free operation is enqueued on the stream rather than blocking the CPU. This enables overlap of allocation, computation, and deallocation across multiple stream operations.

Status

This type allocates from an in-process memory pool and returns buffers to that pool on drop.

Implementations

impl<T: Copy> PooledBuffer<T>

pub fn alloc_async( pool: &MemoryPool, n: usize, _stream: &Stream, ) -> CudaResult<Self>

Asynchronously allocates a buffer of n elements from the given pool.

The allocation is ordered relative to other operations on stream.

Errors

pub fn len(&self) -> usize

Returns the number of T elements in this buffer.

pub fn is_empty(&self) -> bool

Returns true if the buffer contains zero elements.

pub fn byte_size(&self) -> usize

Returns the total size of the allocation in bytes.

pub fn as_device_ptr(&self) -> CUdeviceptr

Returns the raw CUdeviceptr handle.

Trait Implementations

impl<T: Copy> Drop for PooledBuffer<T>

fn drop(&mut self)

Executes the destructor for this type.
