Go doesn't have native async support per se, but its approach to concurrency with goroutines and channels simplifies the process considerably. Synchronous code resembles asynchronous code, eliminating the need to isolate goroutines. Rust, on the other hand, took a different route. Green threads don't integrate smoothly with code interfacing through FFI. Moreover, Rust's async model doesn't require a garbage collector.
