🔒 Rust Mutex §

= a lock on data access

How? §

Normal §

• Mutex<T> -> Mutex::new(T)
• .lock() to acquire the lock
  • blocks until mutex is obtained
  • returns MutexGuard<T>
  • released when variable is dropped

Read, write §

• RwLock
  • .write() waits for exclusive, mut access
    • -> max one writer
  • .read() waits for non-mut access
    • -> many readers

Conditional §

• std::sync::Condvar
  • .wait() -> block thread
  • .notify_all() -> releases blocked (via .wait()) thread
