In the wake of Why is my Rust build so slow?, developers from the mold and lld linkers reached out, wondering why using their linker didn't make a big difference.

Of course the answer was "there's just not that much linking to do", and so any difference between mold and lld was within a second. GNU ld was lagging way behind, at four seconds or so.

I've recently come back to an older project of mine (that powers this website), and as I did some maintenance work: upgrade to newer crates, upgrade to a newer rustc, I noticed that my build was taking too damn long!

For me, this is a big issue. Because I juggle a lot of things at any given time, and I have less and less time to just hyperfocus on an issue, I try to make my setup as productive as possible.

Writing Rust is pretty neat. But you know what's even neater? Continuously testing Rust, releasing Rust, and eventually, shipping Rust to production. And for that, we want more than plug-in for a code editor.

We want... a workflow.

Why I specifically care about this
