Struct PooledBuf

pub struct PooledBuf { /* private fields */ }

PooledBuf is a buffer pool that designed for reusing already allocated bufs.

It works as best-effort that tries to reuse the buffer if possible. It won’t block the thread if the pool is locked, just returning a new buffer or dropping existing buffer.

Implementations

impl PooledBuf

pub fn new(size: usize) -> Self

Create a new buffer pool with a given size.

pub fn with_initial_capacity(self, initial_capacity: usize) -> Self

Set the initial capacity of the buffer.

The default value is 0.

pub fn get(&self) -> BytesMut

Get a BytesMut from the pool.

It’s guaranteed that the buffer is empty.

pub fn put(&self, buf: BytesMut)

Put a BytesMut back to the pool.
