Enum rama::combinators::Either6

pub enum Either6<A, B, C, D, E, F> {
    A(A),
    B(B),
    C(C),
    D(D),
    E(E),

}
Expand description

A type to allow you to use multiple types as a single type.

and will delegate the functionality to the type that is wrapped in the Either type. To keep it easy all wrapped types are expected to work with the same inputs and outputs.

You can use [crate::combinators::impl_either] to implement the Either type for the available number of type parameters on your own Trait implementations.
