Struct BufferPool 

pub struct BufferPool { /* private fields */ }

Device-aware reusable GPU buffer pool.

Implementations

impl BufferPool

pub fn global() -> &'static Self

Return the process-wide buffer pool.

pub fn new() -> Self

Create an empty buffer pool.

pub fn acquire( &self, device: &Device, label: &str, size: u64, usage: BufferUsages, ) -> Result<PooledBuffer>

Acquire a reusable buffer with at least size bytes and exactly usage.

Errors

Returns Error::Gpu when pool metadata cannot be locked.

pub fn release(&self, buffer: PooledBuffer)

Release a buffer to the pool immediately.

pub fn with_buffer<R>( &self, device: &Device, label: &str, size: u64, usage: BufferUsages, f: impl FnOnce(&Buffer) -> R, ) -> Result<R>

Acquire a buffer for the duration of f and release it afterward.

Errors

Returns Error::Gpu when buffer acquisition fails.

impl Clone for BufferPool

fn clone(&self) -> BufferPool

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for BufferPool

fn default() -> BufferPool
