11 //! Useful synchronization primitives
13 //! This module contains useful safe and unsafe synchronization primitives.
14 //! Most of the primitives in this module do not provide any sort of locking
15 //! and/or blocking at all, but rather provide the necessary tools to build
16 //! other types of concurrent primitives.
