Use the term struct-like data instead of anonymous structs for data of struct-like enum variants

[orzechow]

The current term in the docs anonymous structs seems to be outdated.
I'd suggest struct-like data or rephrasing the whole sentence to use struct-like variant.

The terminology used in the Rust Book on enums is

named fields, like a struct

The Reference on enums uses

struct-like enum variant

The term anonymous struct on the other hand is neither mentioned in the Rust book on structs or enums, nor the references on structs or enums.

To me "struct-like data" still seems a bit jargony without it being defined.

or rephrasing the whole sentence to use struct-like variant.

I think that would be my preference if you're able to rephrase it. At least the reference (which is linked) contains that exact phrase so it should be clear what's meant.
