Rust has amazing support for concurrency programming. Today I will cover Mutex, Rc, RefCell, Channels, and Threads. I might make a second post covering the rest of the concepts like Arc. Rust dont have green threads since focus on having zero cost of abstractions. However, using channels we have a powerful abstraction to work with threads. Combined with Rc/Arc and RefCell/Cell we have a good foundation for good concurrency programs. Today I want to share 4 small pocs and 4 videos about Mutex, Rc/RefCell, Threads, and Channels in Rust. Let’s get started!
