[−][src]Struct futures::lock::Mutex
A futures-aware mutex.
Methods
impl<T> Mutex<T>
[src]
pub fn new(t: T) -> Mutex<T>
[src]
Creates a new futures-aware mutex.
pub fn into_inner(self) -> T
[src]
Consumes this mutex, returning the underlying data.
Examples
use futures::lock::Mutex; let mutex = Mutex::new(0); assert_eq!(mutex.into_inner(), 0);
impl<T> Mutex<T> where
T: ?Sized,
[src]
T: ?Sized,
pub fn try_lock(&self) -> Option<MutexGuard<T>>
[src]
Attempt to acquire the lock immediately.
If the lock is currently held, this will return None
.
ⓘImportant traits for MutexLockFuture<'a, T>pub fn lock(&self) -> MutexLockFuture<T>
[src]
ⓘImportant traits for MutexLockFuture<'a, T>
Acquire the lock asynchronously.
This method returns a future that will resolve once the lock has been successfully acquired.
ⓘImportant traits for &'_ mut Fpub fn get_mut(&mut self) -> &mut T
[src]
ⓘImportant traits for &'_ mut F
Returns a mutable reference to the underlying data.
Since this call borrows the Mutex
mutably, no actual locking needs to
take place -- the mutable borrow statically guarantees no locks exist.
Examples
use futures::lock::Mutex; let mut mutex = Mutex::new(0); *mutex.get_mut() = 10; assert_eq!(*mutex.lock().await, 10);
