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.

There’s one thing that bothers me. In part 1, why are we using hyper-staticfile? Couldn’t we just use file:/// URLs?

Well, first off: showing off how easy it is to serve some static files, even in a “scary” language like Rust, is just not something I could pass up.

But also: think about distributing salvage as a tool. Will we want to distribute all those HTML/CSS/JS/font files alongside it?

NO! No no no.

What?

WE WERE DONE!

Well… yes! But also no. We still shell out to a bunch of tools:

$ rg 'Command::new' src/commands/mod.rs 126: let variant = if let Ok(output) = run_command(Command::new("wslpath").arg("-m").arg("/")) { src/commands/cavif.rs 29: Command::new("cavif") src/commands/imagemagick.rs 25: Command::new(&self.bin) src/commands/cwebp.rs 25: Command::new("cwebp") src/commands/svgo.rs 25: Command::new("svgo")

I was a bit anxious about running our poppler meson build in CI, because it’s the real test, you know? “Works on my machine” only goes so far, things have a tendency to break once you try to make them reproducible.

And I was right to worry… but not for the reasons I thought. As I tried to get everything to build in CI, there was a Pypi maintenance that prevented me from installing meson, and then Sourceforge was acting up.

What’s next? Well… poppler is the library Inkscape uses to import PDFs.

Turns out, poppler comes with a bunch of CLI tools, including pdftocairo!

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.
