pulz-arena

A generational arena allocator inspired by [generational-arena] with compact generational indices.

When you insert a value into the arena, you get an index-pointer in return. You can then use this index-pointer to access the provided value.

Example

```rust use pulz_arena::{Arena,Index};

let mut arena = Arena::new();

// insert some elements and remember the returned index let a = arena.insert("foo"); let b = arena.insert("bar");

// access inserted elements by returned index assert_eq!("bar", arena[b]);

// there are also the "checked" versions get and get_mut that returns Option. assert_eq!(Some(&"foo"), arena.get(a));

// items can be removed efficiently assert_eq!(Some("foo"), arena.remove(a)); assert!(!arena.contains(a)); ```

no_std

This crate should also work without std. No additional configuration required.
