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.

Modules

  • Atomic types.
  • Thread synchronization primitives.
  • Threads that can borrow variables from the stack.

Structs

  • Performs exponential backoff in spin loops.
  • Pads and aligns a value to the length of a cache line.
