Rust Tutorial #27: Embedded Rust — no_std and Embassy
In the previous tutorial, we did a collections deep dive. Now we explore Embedded Rust — how Rust works on microcontrollers, what no_std means, and why Rust is becoming the language of choice for embedded systems. This is a conceptual tutorial. The code runs on your regular computer but demonstrates the patterns you use in real embedded Rust. You don’t need hardware to follow along. Why Rust for Embedded? Embedded systems have strict requirements: no crashes, no memory leaks, no undefined behavior. A bug in a pacemaker or car brakes can be fatal. ...
