AS Cap'p Scheme Language <https://capnproto.org/language.html#generic-types>
says: "A *struct or interface* type may be parameterized, making it
“generic”."
I am wondering is it possible (technically) to have *Generic Enums*?
In Rust, this is very common that a method can return "Result" Generic
Enum, that can be an error or a generic value:
enum Result<T, E> {
Ok(T),
Err(E),
}
If technically it is not possible to define a generic enum, what is the
bests practice of define this function in Cap'n Proto:
fn foo() -> Result<String, Error> {
...
}
