std/struct
Struct — the interface every struct satisfies, named or anonymous. Its
sole function, update, returns a copy of a struct with selected fields
replaced, and is reached type-qualified: Struct.update(original, updates).
Import with import std/struct.

The universal struct interface. Every struct value — a named struct type
or an anonymous {...} — satisfies Struct, so its functions are callable on
any of them; no non-struct type satisfies it. Struct is also usable as a
bound (fn f<'T>(x: 'T): 'T where 'T: Struct) and an existential (fn f(s: Struct)).
