Provides a simple trait that unwraps the locks provide by [std::sync::RwLock].

In every case, this is the same as calling .expect("lock poisoned"). However, it does not use .unwrap() or .expect(), which makes it easier to distinguish from other forms of unwrapping when reading code.

use or_poisoned::OrPoisoned;
use std::sync::RwLock;

let lock = RwLock::new(String::from("Hello!"));

let read = lock.read().or_poisoned();
// this is identical to
let read = lock.read().unwrap();
