/// A Condition Variable /// /// Condition variables represent the ability to block a thread such that it /// consumes no CPU time while waiting for an event to occur. Condition /// variables are typically associated with a boolean predicate (a condition) /// and a mutex.

However it is possible to /// switch to a different mutex if there are no threads currently waiting on /// the condition variable. /// /// # Differences from the standard library `Condvar` /// /// - No spurious wakeups: A wait will only return a non-timeout result if it /// ``` /// - `Condvar::notify_all` will only wake up a single thread, the rest are /// requeued to wait for the `Mutex` to be unlocked by the thread that was /// woken up. /// - Only requires 1 word of space, whereas the standard library boxes the /// `Condvar` due to platform limitations. /// - Can be statically constructed. /// - Does not require any drop glue when dropped. /// - Inline fast path for the uncontended case. /// /// # Examples /// /// ``` /// use parking_lot::{Mutex, Condvar}; /// use std::sync::Arc; /// use std::thread; /// /// let pair = Arc::new((Mutex::new(false), Condvar::new())); /// let pair2 = pair.clone(); /// /// // Inside of our lock, spawn a new thread, and then wait for it to start /// thread::spawn(move|| { /// let &(ref lock, ref cvar) = &*pair2; /// let mut started = lock.lock(); /// *started = true; /// cvar.notify_one(); /// }); /// /// // wait for the thread to start up /// let &(ref lock, ref cvar) = &*pair; /// let mut started = lock.lock(); /// if !*started { /// cvar.wait(&mut started); /// } /// // Note that we used an if instead of a while loop above.
