×4ˆ ÅÀ × ÆÀ CondvarÁ<› ‡> ¤,¤ µ> ü šh ü ! Thread parking and unparking.Á " ú ü&n k A [`Parker`] is in either the notified or unnotified state. The [`park()`][`Parker::park()`] method blocksÁ ü•f c the current thread until the [`Parker`] becomes notified and then puts it back into the unnotifiedÁ üüY V state. The [`unpark()`][`Unparker::unpark()`] method puts it into the notified state.Á Ö ú üÚa ^ This API is similar to [`thread::park()`] and [`Thread::unpark()`] from the standard library.Á ü¼b _ The difference is that the state "token" managed by those functions is shared across an entireÁ üŸc ` thread, and anyone can call [`thread::current()`] to access it. If you use `park` and `unpark`,Á üƒ^ [ but you also call a function that uses `park` and `unpark` internally, that function couldÁ üâc ` cause a deadlock by consuming a wakeup that was intended for you. The [`Parker`] object in thisÁ üÆc ` crate avoids that problem by managing its own state, which isn't shared with unrelated callers.Á ª ú ü®I F [`thread::park()`]: https://doc.rust-lang.org/std/thread/fn.park.htmlÁ üø_ \ [`Thread::unpark()`]: https://doc.rust-lang.org/std/thread/struct.Thread.html#method.unparkÁ üØO L [`thread::current()`]: https://doc.rust-lang.org/std/thread/fn.current.htmlÁ ¨ ú t¬ # ExamplesÁ » ú <¿ ```Á ¤Ç use std::thread;Á äÜ use std::time::Duration;Á Äù use parking::Parker;Á ’
