The problem is not the brackets, and the colons and so on, but rather the cultural habit of wanting to cram as many concepts as possible into as few lines as possible. A Rust function has to be generic and fast, it should absolutely use references and also Result types, some functional idiom and generally encode as much as possible in the type system. When other languages would settle for another if or an exception, Rust always has one more weird trick up its sleeve to use instead. This is the curse of the bigbrain programmer wanting to use bigbrain concepts everywhere. Crate and library developers have internalized these lessons and it has become a self-fulfilling prophecy.
