Utilities for concurrent programming
# Crossbeam Utils

[![Build Status](](
[![Rust 1.28+](](

This crate provides miscellaneous tools for concurrent programming:

#### Atomics

* [`AtomicCell`], a thread-safe mutable memory location.<sup>(no_std)</sup>
* [`AtomicConsume`], for reading from primitive atomic types with "consume" ordering.<sup>(no_std)</sup>

#### Thread synchronization

* [`Parker`], a thread parking primitive.
* [`ShardedLock`], a sharded reader-writer lock with fast concurrent reads.
* [`WaitGroup`], for synchronizing the beginning or end of some computation.

#### Utilities

* [`Backoff`], for exponential backoff in spin loops.<sup>(no_std)</sup>
* [`CachePadded`], for padding and aligning a value to the length of a cache line.<sup>(no_std)</sup>
* [`scope`], for spawning threads that borrow local variables from the stack.

*Features marked with <sup>(no_std)</sup> can be used in `no_std` environments.*<br/>
