index-pool

A pool which manages allocation of unique indices. Acts like a psuedo-memory allocator.

toml [dependencies] index-pool = "1.0"

Example

```rust extern crate indexpool; use indexpool::IndexPool;

fn main() { let mut pool = IndexPool::new();

let a = pool.new_id();
let b = pool.new_id();
let c = pool.new_id();

let mut data = vec![""; pool.maximum()];
data[a] = "apple";
data[b] = "banana";
data[c] = "coconut";

// Nevermind, no bananas
pool.return_id(b).unwrap();

let p = pool.new_id();
data[p] = "pineapple";

assert_eq!(data, vec!["apple", "pineapple", "coconut"]);

} ```
