Module sync 

Modules

broadcast

A multi-producer, multi-consumer broadcast queue. Each sent value is seen by all consumers.

mpsc

A multi-producer, single-consumer queue for sending values between asynchronous tasks.

oneshot

A one-shot channel is used for sending a single message between asynchronous tasks. The channel function is used to create a Sender and Receiver handle pair that form the channel.

Structs

Arc

A thread-safe reference-counting pointer. ‘Arc’ stands for ‘Atomically Reference Counted’.

Mutex

An asynchronous Mutex-like type.

Notify

Notifies a single task to wake up.

RwLock

An asynchronous reader-writer lock.

Functions

is_pi_mutex_active

Diagnostic — true when the PI variant is active in this build.

report_lock_protocol

Print, once at boot, which lock protocol this process actually obtained.

Type Aliases

PriorityInheritanceMutex

Non-RT fallback — uses parking_lot::Mutex for the common case. PI semantics are not needed because the scheduler does not preempt the lock holder by priority.

PriorityInheritanceMutexGuard

See PriorityInheritanceMutexGuard — parking_lot’s guard is already !Send for the same reason.
