pub struct IdAllocator<T>(Mutex<IdAllocatorInner<T>>);
Expand description

Manages allocation of numeric IDs.

Note that the current implementation wastes memory. It would be far more efficient to use a compressed bitmap, like https://roaringbitmap.org or the hibitset crate, but neither presently supports a fast “find first zero” operation.

Tuple Fields

0: Mutex<IdAllocatorInner<T>>

Implementations

Creates a new IdAllocator that will assign IDs between min and max, both inclusive.

Allocates a new ID.

Returns None if the allocator is exhausted.

Releases a new ID back to the pool.

It is undefined behavior to free an ID twice, or to free an ID that was not allocated by this allocator.
