Message Passing in Rust Threads is very helpful

Reading Time: 3 minutes Rust has been the most loved programming language for the last five years in a row. It is a low-level statically-typed multi-paradigm programming language that’s focused on safety and performance. Rust has facilities for message passing through an mpsc channel which allows various threads to communicate. Rust solves problems that C/C++ has been struggling with for a long time, such as memory errors and building concurrent programs. Due to the borrow checker, Rust can prevent data races at compile-time. Data races Continue Reading
