Struct BufferPool

Source

pub struct BufferPool { /* private fields */ }

Expand description

A bounded free list whose allocations are safe to reuse on one ordered stream.

Implementations§

Source §

impl BufferPool

Source

pub fn new() -> Arc<Self> ⓘ

Create a pool with the default 512 MiB retained-byte limit.

Source

pub fn with_limit(limit: usize) -> Self

Create a pool with an explicit retained-byte limit.

Source

pub fn acquire( self: &Arc<Self>, stream: &Stream, bytes: usize, ) -> Result<PooledBuffer>

Acquire at least bytes, reusing a block no larger than twice the request.

Source

pub fn cached_bytes(&self) -> usize

Bytes currently retained for reuse.
