//! Core concurrency-enabled mechanisms and primitives.
//!
//! This crate contains the implementations of Rust's core synchronization
//! primitives. This includes channels, mutexes, condition variables, etc.
//!
//! The interface of this crate is experimental, and it is not recommended to
//! use this crate specifically. Instead, its functionality is reexported
//! through `std::sync`.
