Crate pulz_arena[−]
Expand description
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
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.
