Programming in Rust has become so much easier than when I first started. Not only the continuing polish of the core tools (e.g. error message clarity, rustfmt is bundled now) but also the increasing breadth and quality of the libraries available!

Doing another iteration on my diagnostics display. I'm reasonably happy with the bold highlighting within the error message.
I'm not sure about the colour on Warning and Error though. It gives the output some visual structure, but arguably the message itself is more important.
I see that *up has become an increasingly common name for toolchain installers: rustup, ghcup, even juliaup.
I think Rust was the first to use this terminology? I'm curious how similar the different *up tools are.
Coming from JS or Python, imports in Rust feel weird. They're entirely optional aliases for fully qualified symbols, which are always available.
I don't know of many other languages where you can just start using libraries. Java is the only one I can think of.
