Lock Free Object Pool
A thread-safe object pool collection with automatic return and attach/detach semantics.
Some implementations are lockfree :
- LinearObjectPool
- SpinLockObjectPool
Other use std::Mutex :
- MutexObjectPool
And NoneObjectPool basic allocation without pool.
Usage
[]
= "0.1"
extern crate lockfree_object_pool;
Example
The general pool creation looks like this for
let pool = new;
And use the object pool
let mut item = pool.pull;
*item = 5;
...
At the end of the scope item return in object pool.
Interface
All implementations support same interface :
Multithreading
All implementation support allocation/desallocation from on or more thread. You only need to wrap the pool in a [std::sync::Arc
] :
let pool = new;
