Crossbeam Utils

Build Status License Cargo Documentation Rust 1.38+ chat

This crate provides miscellaneous tools for concurrent programming:

Atomics

  • AtomicCell, a thread-safe mutable memory location.(no_std)
  • AtomicConsume, for reading from primitive atomic types with “consume” ordering.(no_std)

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.(no_std)
  • CachePadded, for padding and aligning a value to the length of a cache line.(no_std)
  • scope, for spawning threads that borrow local variables from the stack.

Features marked with (no_std) can be used in no_std environments.

Usage

Add this to your Cargo.toml:

[dependencies]
crossbeam-utils = "0.8"

Compatibility
