Struct Pool

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

A pool of reusable memory.

Implementations

impl<T> Pool<T>

pub fn new<C>(create: C) -> Pool<T>

where C: Fn() -> T + Send + Sync + 'static,

Create a new Pool from an initializer function.

pub fn with_clear<C, D>(create: C, clear: D) -> Pool<T>

where C: Fn() -> T + Send + Sync + 'static, D: Fn(&mut T) + Send + Sync + 'static,

Create a new Pool from an initializer function and a clear function.

The clear function will be called whenever the ItemGuard is dropped, and provides an opportunity to clear values and remove potentially sensitive information from the items before returning it to the memory pool.

Note that drop in Rust is not guaranteed to run, so this function is not a replacement for proper security measures.

pub fn get<'a>(&'a self) -> ItemGuard<'a, T>

Get an item from the pool.

Trait Implementations

impl<T> Clone for Pool<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
