Rust will yell at you if you use specific magic numbers like these

edit: yes, 0xCAFEBABE is a warning but 0xFEEDFACE is not:

I'm surprised they didn't use 0xDECAFBAD for the Java format.

Even more interesting is the Wikipedia page https://en.wikipedia.org/wiki/Hexspeak catalogs a delightfully long list of hexspeak words and what they're used for.

That's a Code of Conduct violation. It's not the 90s anymore, there's no quarter for this type of thing in modern development teams. Rust's style checker even flags up the use problematic magic numbers.
