The first thing I implore everyone to do when evaluating Rust is to check out a non trivial project and start hacking on it. I have always found the compiler to be unacceptably slow in these cases, especially if you come from C rather than C++. If you work your way up from Hello World you may not ever notice this until you already invested a substantial amount of effort.

Is this “just” a 20% project or is this more significant (like Android one day supporting Rust to develop apps)?

And I haven’t looked at everything yet, but it suggests to install Rust like this:

  sudo apt install cargo rust-src
While everyone I know uses rustup^:

  curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
^ https://rustup.rs/

They mention rustup on the 3rd slide.

Could you point me towards a project where this is the case? I want to try it out as I never found Rust slow to compile.

I have never found this to be the case as long as you are using workspaces to split up the compilation units.

I’ve found this to be highly dependent on the hardware you are using. On my 2015 MacBook Pro, Rust was slow enough to be annoying. On my new M1 Pro MacBook (which is ~9x faster), it’s fast enough for me not to notice compile times.

Slower compile times are a small price to pay for memory safety and much higher productivity.

They're using Rust in the android system: https://security.googleblog.com/2022/12/memory-safe-language...
