Rust is also a systems language. I am still wrapping my mind around why it is so popular for so many end projects when its main use case and goals were basically writing a browser a maybe OS drivers.

But that’s precisely why it is good for developer tools. And it turns out people who write systems code are really damn good at writing tools code.

As someone who cut my teeth on C and low level systems stuff I really ought to learn Rust one of these days but Python is just so damn nice for high level stuff and all my embedded projects still seem to require C so here I am, rustless.

If python's painpoints don't bother you enough (or you are already comfortable with all the workarounds,) then I'm not sure Rust will do much for you.

What I like about Rust is ADTs, pattern matching, execution speed. The things that really give me confidence are error handling (right balance between "you can't accidentally ignore errors" of checked exceptions with easy escape hatches for when you want to YOLO,) and the rarity of "looks right, but is subtly wrong in dangerous ways" that I ran into a lot in dynamic languages and more footgun languages.

Compile times suck.

I write scripts in rust as a replacement for bash. Its really quite good at it. Aside from perl, its the only scripting language that can directly make syscalls. Its got great libraries for: parsing, configuration management, and declarative CLIs built right into it.

Sure its a little more verbose than bash one-liners, but if you need any kind of error handling and recovery, its way more effective than bash and doesn't break when you switch platforms (i.e. mac/bsd utility incompatibilities with gnu utilities).

My only complaint would be that dealing with OsString is more difficult than necessary. Way to much of the stdlib encourages programmers to just do "non-utf8 paths don't exist" and panic/ignore when encountering one. (Not a malady exclusive to rust, but I wish they'd gotten it right)
