This past May, I started a new job working in Rust. I was somewhat skeptical of Rust for a while, but it turns out, it really is all it’s cracked up to be. As a long-time C++ programmer, and C++ instructor, I am convinced that Rust is better than C++ in all of C++'s application space, that for any new programming project where C++ would make sense as the programming language, Rust would make more sense.
i can’t speak for the lemmy’s developers but rust is basically the perfect language for backend servers
it’s incredibly fast
it’s incredibly safe
there is clippy, a incredibly powerful tool to detect common mistakes
statically linked libraries (bad for normal applications but ideal for servers, it’s why go does it)
incredibly powerful pattern matching
very safe and easy-to-use generics
sanitized macros
these are just a couple of things that came to mind. for most of rust’s life it was used as a language to create backend servers and dynamically link libraries so it ended up being very good for those things
