I've also heard that Rust compilation is slow, so I put off learning it for a while. I finally dug in deep recently and, to be honest, I don't understand the issue. Rust compilation is quite fast in my experience.

Your comment was the first I've heard of spotifyd, so I downloaded it from github and ran "cargo build". I spent 3 minutes figuring out that I needed to install the "libasound2-dev" package, then I spent less than 2 minutes compiling. I watched the clock to be sure, but after only 2 minutes, Cargo produced a target/debug/spotifyd executable. Maybe you're referring to --release compilation?

I don't have the fastest PC, it's just an 8 year old desktop with a 6 core Intel i7 980x running Ubuntu 18.04. Rust compilation maxes out all the cores, which is really nice.

With the RustEnhanced package added to Sublime Text, editing Rust code is a very interactive experience with practically instant feedback. Running tests is fast too.

I wish I understood why some people are apparently having a very different experience. Maybe it's slow on some operating systems.

Indeed.

Ok, well, "cargo build --release" took 3 minutes and 55 seconds, which I would consider reasonably fast for compiling and optimizing 300+ libraries. I guess your laptop has only 2 cores in an older processor, which would explain the difference. Kudos to you for keeping good hardware alive.

sometimes it takes 100x more without any apparent reason - it's probably because of memory or something, what takes minute to compile on my MBA, sometimes never finishes on raspi3 (swap is off)

I currently compile on raspi4 and scp the results there to check.
