I think it’s reasonable that std library code goes to one extreme of ugly-but-performant while in my own code I can choose something slightly more elegant. Such as avoiding a nested function. So while I agree with some of the points of Rust having a tendency for hiding the what in all the how (and token salad), I think looking at the stdlib isn’t always a good example of idiomatic Rust.
