Creates a new index range inclusive of the start value and exclusive of the end value. ``` let mut arena = la_arena::Arena::new(); let a = arena.allo

Creates a new empty map.

Creates a new index range inclusive of the start value and end value. ``` let mut arena = la_arena::Arena::new(); let foo = arena.alloc("foo"); let b

Ensures a value is in the entry by inserting the default if empty, and returns a mutable reference to the value in the entry.

TODO: make this a non-recursive fn

Reserves capacity for at least additional more elements to be inserted in the map.

Reallocates the arena to make it take up as little space as possible.

Shrinks the capacity of the map as much as possible.

Returns an iterator over the arena’s values. ``` let mut arena = la_arena::Arena::new(); let idx1 = arena.alloc(20); let idx2 = arena.alloc(40); let

Returns an iterator over the values in the map.

Returns an iterator over the arena’s mutable values. ``` let mut arena = la_arena::Arena::new(); let idx1 = arena.alloc(20); assert_eq!(arena[idx1],

Returns an iterator over mutable references to the values in the map.

Create a new empty arena with specific capacity. ``` let arena: la_arena::Arena<i32> = la_arena::Arena::with_capacity(42); assert!(arena.is_empty());

Create a new empty map with specific capacity.
