Enum tower::util::Either

source · [−]

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

Expand description

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.
