This is called union types and golang doesn't have it. If you _want_ this flexibility, you'll have to use `any`. – Sergio Tulentsev Jul 08 '22 at 10:34

3The most appropriate solution will depend on the context (mainly, how the data type will be used). – Hymns For Disco Jul 08 '22 at 10:36

If by `interface{}` you mean the *empty interface* and not interface types in general, then you can declare unions with [General interfaces](https://go.dev/ref/spec#General_interfaces): *"In their most general form, an interface element may also be an arbitrary type term `T`, or a term of the form `~T` specifying the underlying type `T`, **or a union of terms `t1|t2|…|tn`**."* – mkopriva Jul 08 '22 at 10:42
