151-byte static Linux binary in Rust

Part of the sales pitch for Rust is that it's "as bare metal as C".1 Rust can do anything C can do, run anywhere C can run,2 with code that's just as efficient, and at least as safe (but usually much safer). I'd say this claim is about 95% true, which is pretty good by the standards of marketing claims. A while back I decided to put it to the test, by making the smallest, most self-contained Rust
