Crate crossbeam_utils

Miscellaneous tools for concurrent programming.

Atomics

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

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