pub struct MutexWeak<T: ?Sized> { /* private fields */ }
Expand description

MutexWeak is a non-owning reference to a Mutex. MutexWeak is to Mutex as std::sync::Weak is to std::sync::Arc.

Examples

let mutex = Mutex::<u32>::new(0);
let mutex_weak = Mutex::downgrade(&mutex);
let mutex_new = mutex_weak.upgrade().unwrap();

Implementations§

Tries to upgrade the MutexWeak to Mutex. If the Mutex was dropped then the function return None.
