Marshalling directives work in conjunction with
spray.httpx.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
|entity||Unmarshalls the request entity to the given type and passes it to its inner route. Used in conjection with as to convert requests to objects.|
|produce||Uses a marshaller for a given type to produce a completion function for an inner route. Used in conjuction with instanceOf to format responses.|
|handleWith||Completes a request with a given function, using an in-scope unmarshaller for an input and in-scope marshaller for the output.|
