> You have x types of string instead of one or two
Funny how you said X, while there are really only 3 types of strings in standard library. You generally only encounter 2 of them: String and OsString. OsString, while annoying, but it's one of the things that makes rust safe. You only ever deal with 3rd type, CString, when you work with FFI, at which point you better already know how strings work on C.
I feel bad for them. I wanted to fix something in NeoVim's built-in lsp recently and lost all interest because of all the things you have to do to:
- Get parent directory for a path - Create that directory if it exists
Why was I annoyed by that? Well, different OSs use different path separators, in rust this is trivial because `Path` and `PathBuf` are target-specific.
That's not a type of string though, it's a path, the fact that it uses `OsString` underneath is irrelevant.

There isn't really anything special to learn about it them, though? I doubt newbie encounter this while learning. Slices are the same thing, you just can't extend it, what is there to learn?
So all in all, about a dozen kinds of strings.
