[−][src]Enum tower::util::Either

pub enum Either<A, B> {
    A(A),
    B(B),
}

Combine two different service types into a single type.

Both services must be of the same request, response, and error types. Either is useful for handling conditional branching in service middleware to different inner service types.

Variants

A(A)

One type of backing Service.

B(B)

The other type of backing Service.
