What is Mutex<T>?

Mutex stands for mutual exclusion. Unlike Cell and RefCell, Mutex are thread-safe meaning it can be used with multiple threads safely, It does so by providing exclusive lock. By having an exclusive lock, Rust ensures that only one thread can change the data at any given time hence avoiding data races.

The data can be only accessed via lock and try_lock which ensures that the data is only accessed when the mutex is locked.

Poisoning

Mutex uses a concept called poisoning where it is considered poisoned when a thread panics while holding the mutex. If the Mutex has been poisoned then all ...
