Struct std::sync::ReentrantLockGuard
source · pub struct ReentrantLockGuard<'a, T: ?Sized + 'a> { /* private fields */ }
🔬This is a nightly-only experimental API. (
reentrant_lock
#121440)Expand description
An RAII implementation of a “scoped lock” of a re-entrant lock. 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
implementation.
This structure is created by the lock
method on
ReentrantLock
.
§Mutability
Unlike MutexGuard
, ReentrantLockGuard
does not
implement DerefMut
, because implementation of
the trait would violate Rust’s reference aliasing rules. Use interior
mutability (usually RefCell
) in order to mutate
the guarded data.
