pub struct Pool<T: PooledObject> { /* private fields */ }

A pool of some objects of type T.

Implementations

impl<T: PooledObject> Pool<T>

pub fn new(cap: usize) -> Self

Returns a new pool with a maximum capacity of cap. This capacity is fixed over the lifetime of the pool.

pub fn put(&self, object: T)

Puts back an object into the pool.

pub fn put_many(&self, objects: impl Iterator<Item = T>)

Puts back an object into the pool.

pub fn take(&self, clear: impl FnOnce(&mut T), new: impl FnOnce() -> T) -> T

Takes an object from the pool or creates a new one.

pub fn dropped_count(&self) -> usize

Returns the number of pages dropped by the pool because the pool was at capacity.

pub fn new_allocated_count(&self) -> usize

Returns the number of fresh objects allocated through the pool.

pub fn reused_count(&self) -> usize

Returns the number of objects reused from the pool.

pub fn returned_count(&self) -> usize

Returns the number of objects returned to the pool.
