Struct guardian::RcMutexGuardian

pub struct RcMutexGuardian<T: 'static> { /* private fields */ }

An RAII implementation of a “scoped lock” of a mutex. When this structure is dropped (falls out of scope), the lock will be unlocked. Keeps a handle to an Rc so that the lock is not dropped until the guard is.

The data protected by the mutex can be access through this guard via its Deref and DerefMut implementations.

Implementations

impl<T> RcMutexGuardian<T>

pub fn take(handle: Rc<Mutex<T>>) -> LockResult<RcMutexGuardian<T>>

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

This function will block the local thread until it is available to acquire the mutex. Upon returning, the thread is the only thread with the mutex held. An RAII guardian is returned to allow scoped unlock of the lock. When the guard goes out of scope, the mutex will be unlocked. The guardian also holds a strong reference to the lock’s Rc, which is dropped when the guard is.

Errors

If another user of this mutex panicked while holding the mutex, then this call will return an error once the mutex is acquired.

Trait Implementations

impl<T> Deref for RcMutexGuardian<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T> DerefMut for RcMutexGuardian<T>

fn deref_mut(&mut self) -> &mut T

Mutably dereferences the value.

impl<T> From<Rc<Mutex<T>>> for RcMutexGuardian<T>

fn from(handle: Rc<Mutex<T>>) -> Self

Converts to this type from the input type.
