Struct BufferPool 

pub struct BufferPool { /* private fields */ }

Implementations

impl BufferPool

pub const DEFAULT_BUFFER_SIZE: usize

pub const DEFAULT_POOL_SIZE: usize = 10

pub fn new(buffer_size: usize, max_pool_size: usize) -> Self

pub async fn get(&self) -> Vec<u8>

A Vec<u8> with capacity buffer_size (or more). If the pool is empty, allocates a fresh one.

pub async fn return_buffer(&self, buf: Vec<u8>)

Returns buf to the pool, shrinking it if it has grown past 2x the configured size. If the pool is full, the buffer is dropped.

pub async fn prewarm(&self, count: usize)

Pre-allocates count buffers at startup so the first request does not pay the allocation cost.

pub fn buffer_size(&self) -> usize

Trait Implementations

impl Default for BufferPool

fn default() -> Self

Returns the “default value” for a type.
