Making A Mutex from Scratch in Rust to Understand Thread Safetyhttps://www.reddit.com/r/programming/comments/1xav3jo/making_a_mutex_from_scratch_in_rust_to_understand
Hey r/programming ! I wrote a comprehensive article on constructing a mutex from scratch. It covers: - Data races: what happens at the register level, and how parallel access can go wrong - Atomics & Memory Ordering: why atomics work and what each memory ordering does (Aq/Rel/AqRel/SeqCst) - Spin lock & Guards: Building a simple mutual exclusion lock via an AtomicBool, and providing safe access to the protected data - And finally, Mutexes: A more complex mutual exclusion primitive that can achieve better performance via thread::park/::unpark The article benchmarks and compares the performance…
