Initial builds are indeed quite slow, especially when a project has a lot of dependencies. However, in most cases further builds are not that bad. I have never built Alacritty from source so I don't really know if there are any specific issues with it, but from my experience incremental builds take just a few seconds in medium sized projects. Additionally during development a full build is usually not necessary all the time; oftentimes it's just enough to check the code for errors with `cargo check`, which is usually significantly quicker than building a full debug binary. Edit: I tested building Alacritty from source on my computer (Ryzen 5600X, Windows 10). The initial build (consisting of 130 crates) took 34 seconds. Building again after adding a single print statement took 6 seconds, and `cargo check` took about half at 3 seconds. It's not ideal by any means, but IMO it's not also unreasonable for 25K lines of code, plus those ~130 dependencies.
