Expand descriptionAn RAII implementation of a “scoped lock” of a mutex. When this structure is
dropped (falls out of scope), the lock will be unlocked.
The data protected by the mutex can be accessed through this guard via its
Deref and DerefMut implementations.
This structure is created by the lock and try_lock methods on
Mutex.
Implementations§
🔬This is a nightly-only experimental API. (mapped_lock_guards #117108)
Makes a MappedMutexGuard for a component of the borrowed data, e.g.
an enum variant.
The Mutex is already locked, so this cannot fail.
This is an associated function that needs to be used as
MutexGuard::map(...). A method would interfere with methods of the
same name on the contents of the MutexGuard used through Deref.
🔬This is a nightly-only experimental API. (mapped_lock_guards #117108)
Makes a MappedMutexGuard for a component of the borrowed data. The
original guard is returned as an Err(...) if the closure returns
None.
The Mutex is already locked, so this cannot fail.
This is an associated function that needs to be used as
MutexGuard::filter_map(...). A method would interfere with methods of the
same name on the contents of the MutexGuard used through Deref.
Trait Implementations§On platforms that use POSIX threads (commonly referred to as pthreads) there is a requirement to
release mutex locks on the same thread they were acquired.
For this reason, MutexGuard must not implement Send to prevent it being dropped from
another thread.

🔬This is a nightly-only experimental API. (pin_ergonomics #130494) Execute the destructor for this type, but different to Drop::drop, it requires self
to be pinned. Read moreT must be Sync for a MutexGuard<T> to be Sync
because it is possible to get a &T from &MutexGuard (via Deref).
