idalloc

A library for different methods of allocating unique identifiers efficiently.

Provided methods:

• Slab - Allocates id in a slab-like manner, handling automatic
  reclamation by keeping a record of which identifier slot to allocate next.

Examples

let mut alloc = idalloc::Slab::<u32>::new();
assert_eq!(0u32, alloc.next());
assert_eq!(1u32, alloc.next());
alloc.free(0u32);
