I think it's not that much the specific parts as it is the combination of (sometimes obscure) symbols forming dense blocks of sigils that you have to carefully pick apart to understand what the code is doing. It's easier to reason about code if it uses words instead of symbols, and Rust seems to desperately want to avoid using actual words (I don't count "fn" as a word, and "pub" is a word, but for me it's somewhere where you go to have a drink after work). Ok, I know there is a long tradition of doing this in C-family languages, but Rust has driven it to new heights, and it has a lot more concepts (with their attached symbols) that you have to keep in your head.

I hate the unpronounceable sigils of languages like Haskell, but C-style abbreviations don't really bother me somehow. The abbreviations help you remember what the words are, at least, and for me this seems to be enough.
