Handlebox

Handlebox is a simple map-like collection that reuses unused keys. Right now it's hard-coded to use u32 keys.

To install, add this line to your Cargo.toml:

toml [dependencies] handlebox = "0.3.0"

Note that Handlebox has not yet reached version 1.0, so the API may change drastically between releases.

Example

```rust use handlebox::*;

// Creating let mut c = HandleBox::new();

// Adding values let h1 = c.add(888);

// Accessing values assert_eq!(c.get(&h1).unwrap(), &888);

// Removing values c.remove(&h1);

// You can access the internal BTreeMap with the .map field assert_eq!(c.map.values().len(), 0); ```
