spin-rs =========== [](https://travis-ci.org/mvdnes/spin-rs) [](https://crates.io/crates/spin) [](https://docs.rs/spin/) This Rust library implements a simple [spinlock](https://en.wikipedia.org/wiki/Spinlock), and is safe for `#[no_std]` environments. Usage ----- Include the following code in your Cargo.toml ```toml [dependencies.spin] version = "0.5" ``` Example ------- When calling `lock` on a `Mutex` you will get a reference to the data. When this reference is dropped, the lock will be unlocked. ```rust extern crate spin; fn main() { let mutex = spin::Mutex::new(0); let rw_lock = spin::RwLock::new(0); // Modify the data { let mut data = mutex.lock(); *data = 2; let mut data = rw_lock.write(); *data = 3; } // Read the data let answer = { let data1 = mutex.lock(); let data2 = rw_lock.read(); let data3 = rw_lock.read(); // sharing (*data1, *data2, *data3) }; println!("Answers are {:?}", answer); } ``` To share the lock, an `Arc<Mutex<T>>` may be used. Remarks ------- The behaviour of these lock is similar to their namesakes in `std::sync`. they differ on the following: - The lock will not be poisoned in case of failure;
