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.
• 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.

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.
