Module sync

Higher level synchronization primitives.

These are modeled after the synchronization primitives in std::sync and those from crossbeam-channel, in as much as it makes sense.

Modules

atomic

Re-export portable atomic.

channel

Close-to-Zephyr channels

Structs

Arc

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

Condvar

Inspired by std::sync::Condvar, implemented directly using z_condvar in Zephyr.

Mutex

A mutual exclusion primitive useful for protecting shared data.

MutexGuard

An RAII implementation of a “scoped lock” of a mutex. When this structure is dropped (faslls out of scope), the lock will be unlocked.

PinWeak

Safe Pinned Weak references.

SpinMutex

A lower-level mutual exclusion primitive for protecting data.

SpinMutexGuard

An RAII implementation of a “scoped lock” of a SpinMutex. When this structure is dropped (falls out of scope), the lock will be unlocked.

Weak

Weak is a version of Arc that holds a non-owning reference to the managed allocation. The allocation is accessed by calling upgrade on the Weak pointer, which returns an Option<Arc<T>>.

Enums

TryLockError

An enumeration of possible errors associated with a TryLockResult.

Type Aliases

LockResult

Until poisoning is implemented, mutexes never return an error, and we just get back the guard.

TryLockResult

The return type from Mutex::try_lock.
