//! This library provides implementations of `Mutex`, `RwLock`, `Condvar`,
//! `Barrier`, and `Once` that are smaller and faster than those in the Rust
//! standard library. It also provides a `ReentrantMutex` type.
//!
//! Everything is powered by lock-free thread queues in userspace
//! which allows the synchronization primitives to be 1 word (`usize`) large.
//! All thread blocking is done through [`std::thread::park`] for maximum portability.
