Lint suggesting to replace str::bytes().count() with str::len() #8083
Description
What it does
It checks for str::bytes().count() and suggests replacing it with str::len() that does the same but shorter and possibly more performant.
Extra: can something like this be done for https://doc.rust-lang.org/std/io/trait.Read.html#method.bytes too?
