alloc-from-pool

This crate implements object pool.

Basic usage

```rust use allocfrompool::Pool;

// dummy struct struct Foo([u8; 50]);

// pool has size = 0 by default let pool = Pool::::new();

// performs allocation let foo1 = pool.alloc(Foo([1; 50])); // returns memory back to pool drop(foo1);

// re-uses the value that we've just returned back to pool let foo2 = pool.alloc(Foo([2; 50])); // returns memory back to pool drop(foo2);

// it also possible to create a Factory based on a pool // that holds a reference to initial Pool let factory = pool.factory(); // Factory has the same alloc method: let foo3 = factory.alloc(Foo([3; 50])); // it uses the same pool, and also returns back to the same pool drop(foo3); ```
