cajeta.concurrent

Atomics, locks, channels and fibers. Fibers are stackful, so the spawn, footprint and wake rows are read against goroutines and virtual threads.

Page
AtomicInt64The lock-free atomic int64 cell
AtomicInt32The lock-free atomic int32 cell
MutexFused mutual exclusion and the data it protects
RwLockThe reader-writer lock for read-heavy shared state
LockThe no-data RAII gate
SemaphoreThe counting permit pool
ChannelThe bounded multi-producer multi-consumer queue, measured with the crossbeam-channel harness shapes: 5M messages, four threads
FiberSleeping the calling fiber
FiberLocalAmbient per-request state
TasksTask utilities: spawn and await
