Expand description

Basic operations for a mutex.

Types implementing this trait can be used by Mutex to form a safe and fully-functioning mutex type.

Safety

Implementations of this trait must ensure that the mutex is actually exclusive: a lock can’t be acquired while the mutex is already locked.

Associated Types

Marker type which determines whether a lock guard should be Send. Use one of the GuardSend or GuardNoSend helper types here.

Associated Constants

Initial value for an unlocked mutex.

Required methods

Acquires this mutex, blocking the current thread until it is able to do so.

Attempts to acquire this mutex without blocking. Returns true if the lock was successfully acquired and false otherwise.

Unlocks this mutex.

Safety

This method may only be called if the mutex is held in the current context, i.e. it must be paired with a successful call to lock, try_lock, try_lock_for or try_lock_until.

Provided methods

Checks whether the mutex is currently locked.
