How does parking_lot compare to std Mutex

parking_lot provides faster, fairer, and more flexible synchronization primitives than std Mutex by using adaptive spinning and avoiding platform-specific deadlocks. It is the preferred choice for high-performance concurrent Rust code.

use parking_lot::Mutex;

let data = Mutex::new(0);
let lock = data.lock();

Unlike std::sync::Mutex, parking_lot::Mutex does not panic on poison; it returns an error type you must handle, allowing you to decide how to recover from a thread panic.

Think of parking_lot as a high-performance upgrade to the standard Rust lock. It waits less time when threads are fighting for access and handles crashes more gracefully. You use it when your program needs to be faster or more reliable under heavy load.
