I don't want praise and ads, I want honest and clear points: what good and what not so good.
Good:
Not so good:
Overall, I like Rust a lot. I think its reputation as a great language is well-deserved. It's not an "easy" language to use, but it prevents so many footguns... It takes me longer to get to a working prototype in Rust. But the first time it compiles successfully... it's probably right.
If I'm working on a project that needs to be fast, I'll reach for Rust over C these days.
I absolutely love the borrow checker. When I do stupid things, instead of me debugging segfaults in prod a week later, it goes "here dumdum, that won't work"
Rust gives me better safety than popular high level languages because it is properly typed AND C++ like performance.
In the past I'd always be forced to choose between:
fast development, slow runtime, big fat VM to lug around, no segfaults
slow development, fast runtime, no VM, segfaults
With Rust I finally get both! Fast development, fast runtime, no VM, no segfaults. It's a dream come true.
I get that there are some half-gods with 30 years of experience that can write safe and reliable C++, but I am not as smart as them nor have I 30 years to learn. And thrn again, even the best C++ developers still occasionally write memory management bugs. It's been more than a decade since I've actually been happy with a new programming language, and I love it.
Thanks, you comment definitely makes me want to try Rust.
Could you tell me, can I use Rust as general purpose application language? Something like: create small executable app (win,unix,mac) that read some files, and do something with it, create GUI app that connects to DB and do something with it, etc?
Yesbut...
Rust's GUI frameworks are all (afaik) still pretty early and a little clunky to use.
...and compiling for Windows is a little clunky.
From a purely yes/no perspective, you can absolutely use Rust for building desktop GUI apps... But I'd recommend using a different language unless your app has really tight performance requirements.
If you want to make a cross platform app with good GUI support, I'd a actually recommend checking out Godot. It's technically a game engine, but the built in scripting language (gdscript) and GUI components are really great. If gdscript is too slow for your purposes you can swap in a lot of other languages (including Rust) though C# is the best supported of these.
