Module futex

Structs§

COMPLETE 🔒: Initialization has completed and all future calls should finish immediately. By choosing this state as the all-zero state the is_completed check can be a bit faster on some platforms.
INCOMPLETE 🔒: No initialization has run yet, and no thread is currently using the Once.
POISONED 🔒: Some thread has previously attempted to initialize the Once, but it panicked, so the Once is now poisoned. There are no other threads currently accessing this Once.
QUEUED 🔒: May only be set if the state is not COMPLETE.
RUNNING 🔒: Some thread is currently attempting to run initialization. It may succeed, so all future threads need to wait for it to finish.
