> Also the fact that it doesn't detect locking the same mutex twice Reentrant mutexes https://en.wikipedia.org/wiki/Reentrant_mutex need interior mutability in Rust, i.e. you'd need something like ReentrantMutex<RefCell<T>>. You can't just lock the mutex and get a &mut T out of it, because then locking the mutex again would get you a second &mut T which would violate Rust's no-aliasing semantics for &mut. The Rust standard library AIUI does not provide this yet. |
