That's what Rust has byte slices for: `b"abcdef"`

  One cannot use string library in Rust against byte slices. For example, regexp works only against strings making it unsuitable for processing, say, log files, that may contain non-utf8 bytes.

    Yea, also found that limitation of the regex library pretty annoying. But conceptually this has nothing to do with string slices being different from byte slices... It might encourage it though.

      FWIW, I think getting the underlying string representation right (and relatedly how it interacts with byte buffers/slices) is really hard. So far, I think Perl 6 probably has the most well thought out structure with regard to that, but they took a decade and a half and lots of testing to come up with what they did. Then again, how it works in Perl 6 is also a function of how the language functions, so it wouldn't be a a direct mapping of concepts, but there are some really good ideas there.

    This is somewhat incorrect, as Rust doesn't have a standard regex library. You're likely thinking of burntsushi's regex crate, which made its own decision to be Unicode-aware. There's no reason that someone couldn't come up with their own regex library (or fork burntsushi's, or just wrap an existing C regex library) that works as you desire.
