> Have you ever tried to recompile 1 yr old code in Rust with the latest compiler? I have, more than once; it worked perfectly fine. The only time it's broken for me is when the code had unstable nightly-only features, hidden behind a "nightly-only" feature flag, which was rejected by the parser on a newer Rust compiler, even though it would not be compiled due to the feature flag being disabled (even though it wouldn't be compiled, it still had to be parsed; IIRC, it was the change to the inline assembly syntax, and the fix was just to change from "asm" to "llvm_asm").
