Macro frunk::Coprod [−]
macro_rules! Coprod { ( ) => { ... }; ( ... $ Rest : ty ) => { ... }; ( $ A : ty ) => { ... }; ( $ A : ty , $ ( $ tok : tt ) * ) => { ... }; }
Returns a type signature for a Coproduct of the provided types
This is a type macro (introduced in Rust 1.13) that makes it easier to write nested type signatures.
Examples
type I32Bool = Coprod!(i32, bool); let co1 = I32Bool::inject(3); // Use ...Tail to append another coproduct at the end. let co2 = <Coprod!(&str, String, ...I32Bool)>::inject(3);Run
