Struct BufferPool 

pub struct BufferPool { /* private fields */ }

Pool of reusable BufferChunk allocations for serialisation and framing.

Implementations

impl BufferPool

pub fn with_config( config: &BufferConfig, custom_allocator: &Option<Arc<dyn ChunkAllocator>>, ) -> BufferPool

Creates a BufferPool from a BufferConfig and an optional ChunkAllocator

pub fn get_buffer(&mut self) -> Option<BufferChunk>

Returns a reusable buffer if one is currently available.

The pool first tries to reclaim an unlocked returned buffer and only allocates a fresh chunk if the configured pool limit still allows it.

pub fn return_buffer(&mut self, buffer: BufferChunk)

Returns a buffer to the pool after use.

pub fn drain_returned(&mut self) -> Drain<'_, BufferChunk>

Drains all returned buffers from the pool in oldest-to-newest order.

pub fn get_pool_sizes(&self) -> (usize, usize)

Returns the number of allocated buffers and the current number of buffers in the pool Returns the number of allocated buffers and the current number of idle buffers in the pool.
