I recently started learning rust, and I was ready for one hell of a fight. I heard all those horror Storys about the compiler complaining about every single detail and that developing rust means having a constant fight with the compiler about seemingly irrelevant things. However, so far I have to tell, that while its somewhat true, that the compiler is somewhat picky, it is incredibly helpful. Never before have I seen such good and helpful compiler messages. It not only says what you did wrong, but also gives direct help on what to do to fix your code. I also really like, that it gives you direct references to the rust book in the compiler messages.
Prior to starting my journey with rust I did quite a lot of python, some C and some bash and their interpreter/compiler messages are nothing when comparing them with rust. Especially the bash error messages are awful if you do not know what they mean and how to fix them.
@cows_are_underrated The simplest way I’ve found to do that is to convert the string into a Vec<char>. UTF-8 strings aren’t optimized for random access because of multi-byte chars.
To array of chars:
let c = s.chars().collect::<Vec<char>>();
And back to string:
let s = c.into_iter().collect::<String>();
