How to automatically marshall Boolean and other basic types to Json?

[Nicolau Werneck]

I am playing around with akka-http 1.0-RC3. I can successfully serve `case class` objects marshalled into JSON, that's just fine. But I am unable to let the server marshall basic types that could be translated to JSON, e.g. integer or Boolean. Shouldn't just `import DefaultJsonProtocol._` be sufficient for the implicit conversions to happen? What else is missing? And how could I write a custom marshaller for a type like this? I haven't been able to find a good example yet...

Hi Nicolau,

can you expand a bit more on your usecase?

A valid root object of the JSON document is only an object or an array. Therefore you can not marshall a single boolean or integer to JSON document. You must have a collection or a case class holding such a value.
