I have some ten-year-old Rust code that would disagree with you. :) [edit -- and yes, it's pre-1.0 code. Not trying to be sneaky, just trying to clarify that the backwards-compatibility guarantee only goes back to a reasonable point in time.]

That's some impressively old rust code — from long before the initial release of the language!

  Might we say that their code has rusted?

    Hahah, that is definitely true. :)

  To be fair, pre-1.0 Rust was already heavily hyped and available. It's not hard to find plenty of projects from that time.

Rust 1.0 came out 6 years ago. There’s no need to sow confusion by referring to pre-1.0 code here.

  That's a major version, yes, but not necessarily sowing confusion. Users have needs that often last longer than 6 years. I got a call last week to update a machine that's running VB 4 code from the mid-90s. It's a spot welder; the casting and transformers are from the 1940s, but the weld controller speaks RS-232 and is from the late 80s. I feel safe assuming the machine will still be in use long after I'm dead. We did a quick update with the original source code to fix a glaring bug that a new operator happened across, but they would like to add a simple database integration feature. The interface simple enough that the update will be a nearly complete rewrite; we'll retain the .ini settings files and custom CSV file format. However, we will be choosing a platform that should last as long as the original. That platform will not be some new hot JS framework that's going to be marked end-of-life before the warranty is up. Not everyone is on a 2-year treadmill!

    There's a big difference between maintaining backwards compatibility with VB4 and VB pre-1.0.

    The point of it being pre-1.0 is not that it was a different major version, but that it had not reached the first major version. pre-1.0 versions were explicitly ALPHA software subject to constant change as indicated in release announcements e.g. https://mail.mozilla.org/pipermail/rust-dev/2014-October/011267.html https://mail.mozilla.org/pipermail/rust-dev/2014-October/011...
