rbtree = "0.1"
```
and this to your crate root:
```rust
extern crate rbtree;
```
How to use
```rust
use rbtree::RBTree;
let mut m = RBTree::new();
assert_eq!(m.len(), 0);
m.insert(1, 2);
assert_eq!(m.len(), 1);
m.insert(2, 4);
assert_eq!(m.len(), 2);
assert_eq!(*m.get(&1).unwrap(), 2);
assert_eq!(*m.get(&2).unwrap(), 4);
```
## Bench
