Marshalling Directives
Marshalling directives work in conjunction with akka.http.scaladsl.marshalling and akka.http.scaladsl.unmarshalling to convert a request entity to a specific type or a type to a response.
See marshalling and unmarshalling for specific serialization (also known as pickling) guidance.
Marshalling directives usually rely on an in-scope implicit marshaller to handle conversion.
Understanding Specific Marshalling Directives
| directive | behavior |
|---|---|
| completeWith | Uses a marshaller for a given type to produce a completion function for an inner route. Used in conjunction with instanceOf to format responses. |
| entity | Unmarshalls the request entity to the given type and passes it to its inner route. Used in conjunction with as to convert requests to objects. |
| handleWith | Completes a request with a given function, using an in-scope unmarshaller for an input and in-scope marshaller for the output. |
