moirai-sync

Synchronization primitives for the Moirai concurrency library. The crate re-exports std::sync's Mutex, RwLock, Condvar, and Barrier unchanged and adds only primitives whose behavior std does not provide:

• FutexMutex — adaptive spinning with futex-backed waiting on Linux.
• WaitGroup — Go-style completion counter.
• ConcurrentHashMap — segment-based locking, with poisoning surfaced as a typed SegmentPoisoned error rather than a panic.
• ShardedResourcePool — sharded pooling of reusable resources.
• LockFreeStack (re-exported from moirai-core) and AtomicCounter (re-exported from moirai-utils).

[dependencies]
moirai-sync = "0.5"

use moirai_sync::{FutexMutex, WaitGroup};

let mutex = FutexMutex::new(0u32);
{
    let mut guard = mutex.lock(); // returns the guard directly, not a Result
    *guard += 1;
}

let wg = WaitGroup::new();
wg.add(1);
wg.done();
wg.wait();
