If your okay with macros, probably nightly only, then it seems reasonable.

There is also slice matching on stable, which let's you match on parts of slices: https://github.com/rust-lang/rust/pull/67712/ . It went out in 1.42. It has some stuff which makes binary stuff easier, but not by much. But perhaps someday you'll get native binary matching in the language that's closer to what Erlang offers.

It made it in the 1.42 release.
