deadlock

Thread-safe slot map and slot min-heap with stable RAII handle. Values are stored by handle; dropping the handle removes the value. The map is sharded to reduce contention; the heap supports peek and stable references into elements.

Example

use deadlock::{SlotMap, SlotHeap};

let map = SlotMap::new();
let id = map.insert(42);
assert_eq!(*id.get(), 42);

let heap = SlotHeap::new();
let (id1, _) = heap.insert(3);
let (id2, _) = heap.insert(1);
let (id3, _) = heap.insert(2);
assert_eq!(*heap.peek().unwrap(), 1);
assert_eq!(*id3.get(), 2);
