Async Rust with Tokio: Futures, Streams, and Channels — and How They Compare to Go
·8 mins
Go’s concurrency model is famously approachable: goroutines are lightweight, channels are built into the language, and context handles cancellation without much ceremony. But Rust’s async story — built on stackless futures, the Tokio runtime, and a rich channel ecosystem — is compelling in a different way. It pushes more decisions to compile time, eliminates data races by construction, and delivers higher concurrency density with less memory.
This post works through Rust async from first principles and puts it side-by-side with Go at every step.
