Nit: "string literals" have type &'static str, so the extra & operators are unnecessary. (This prefix ends up with triple pointer indirection &&&str since .iter() adds another one! But by-value array iteration requires Rust 1.53)

Ah, I got confused since I started with b"pre" instead of b"pre", which doesn't work since the items differed in size, but it does not apply to &'static str, as you mentioned.
We're gonna have to wait for Debian Bookworm for 1.53 I'm pretty sure. ;)

Ah yes, I only mentioned by value iteration in passing :)

SimonSapin: Nit: `"string literals"` have type `&'static str`, so the extra `&` operators are unnecessary.
