}
Expand description
An “either” type specialized for body types.
It is common, in middleware especially, to conditionally return an inner service’s unknown/
generic body B
type or return early with a new response. This type’s “right” variant
defaults to BoxBody
since error responses are the common case.
For example, middleware will often have type Response = ServiceResponse<EitherBody<B>>
.
This means that the inner service’s response body type maps to the Left
variant and the
middleware’s own error responses use the default Right
variant of BoxBody
. Of course,
there’s no reason it couldn’t use EitherBody<B, String>
instead if its alternative
responses have a known type.
