[−][src]Struct async_dup::Mutex
A mutex that implements async I/O traits.
This is a blocking mutex that adds the following impls:
impl<T> AsyncRead for Mutex<T> where &T: AsyncRead + Unpin {}
impl<T> AsyncRead for &Mutex<T> where &T: AsyncRead + Unpin {}
impl<T> AsyncWrite for Mutex<T> where &T: AsyncWrite + Unpin {}
impl<T> AsyncWrite for &Mutex<T> where &T: AsyncWrite + Unpin {}
impl<T> AsyncSeek for Mutex<T> where &T: AsyncSeek + Unpin {}
impl<T> AsyncSeek for &Mutex<T> where &T: AsyncSeek + Unpin {}
Implementations
impl<T> Mutex<T>
[src]
pub fn new(data: T) -> Mutex<T>
[src]
pub fn lock(&self) -> MutexGuard<T>
[src]
Acquires the mutex, blocking the current thread until it is able to do so.
Returns a guard that releases the mutex when dropped.
Examples
use async_dup::Mutex; let mutex = Mutex::new(10); let guard = mutex.lock(); assert_eq!(*guard, 10);
pub fn try_lock(&self) -> Option<MutexGuard<T>>
[src]
Attempts to acquire the mutex.
If the mutex could not be acquired at this time, then None
is returned. Otherwise, a
guard is returned that releases the mutex when dropped.
Examples
use async_dup::Mutex; let mutex = Mutex::new(10); if let Some(guard) = mutex.try_lock() { assert_eq!(*guard, 10); }
pub fn into_inner(self) -> T
[src]
Consumes the mutex, returning the underlying data.
Examples
use async_dup::Mutex; let mutex = Mutex::new(10); assert_eq!(mutex.into_inner(), 10);
pub fn get_mut(&mut self) -> &mut T
[src]
Returns a mutable reference to the underlying data.
Since this call borrows the mutex mutably, no actual locking takes place -- the mutable borrow statically guarantees the mutex is not already acquired.
Examples
use async_dup::Mutex; let mut mutex = Mutex::new(0); *mutex.get_mut() = 10; assert_eq!(*mutex.lock(), 10);
