Struct BufferPoolRef 

pub struct BufferPoolRef { /* private fields */ }

Cheap, clonable handle to a per-thread buffer pool.

Use BufferPoolRef::acquire to get an OwnedReadBuffer; when the guard is dropped, the buffer is automatically returned to the pool.

Implementations

impl BufferPoolRef

pub fn acquire<const CHUNK_SIZE: usize, const INITIAL_CAPACITY: usize>( &self, ) -> OwnedReadBuffer<CHUNK_SIZE, INITIAL_CAPACITY>

Acquire a buffer from the pool (or allocate a new one) and wrap it in an RAII guard that returns the buffer on Drop.

pub fn release<const CHUNK_SIZE: usize, const INITIAL_CAPACITY: usize>( &self, buffer: ReadBuffer<CHUNK_SIZE, INITIAL_CAPACITY>, )

Return a buffer to the pool.

You typically don’t need to call this directly. Dropping OwnedReadBuffer does it for you.
