Arc in Rust's std::sync module allows multiple threads to share ownership of data by using atomic operations to track reference counts, ensuring data is dropped only when all references are gone.
Mutex, another synchronization primitive in std::sync, ensures that only one thread can access shared data at a time, preventing data races by requiring a lock before access.
Combining Arc and Mutex in Rust provides a safe way to share and mutate data across threads, essential for building concurrent systems.
Arc enables safe shared ownership by allowing multiple threads to access the same value, deallocating it only when the last reference is dropped.
Mutex provides controlled mutability by allowing exclusive access to data, ensuring thread-safe writes.
Combining Arc> is a common pattern in Rust for sharing mutable state across threads, preventing data races at compile time.
Using Arc> allows for safe sharing and mutation of state across threads in Rust, ensuring robust and performant concurrent programs.
Arc and Mutex work together to provide a powerful abstraction for concurrent programming in Rust, with Arc handling shared ownership and Mutex ensuring exclusive access.
Arc> is an intuitive and effective tool for a wide range of use cases, such as caches, counters, and background task coordination.
By combining Arc and Mutex with channels, Rust enables safe task distribution and coordination among multiple threads, ensuring thread-safe shared state.
