Rust is extremely unreadable if you're not used to it, but becomes one of the most readable languages once you are. My subjective experience, at least.
I love Rust, but would disagree. It is always difficult to read partially because there is so much boilerplate. impl blocks and where clauses in some codebases cause a lot of noise, for example. Granted, it probably could not be as easy to read as say a subset of Python is, for example, simply because it is a very strongly typed systems language and therefore needs to describe a lot more.
