Extracts the client's IP from either the X-Forwarded-For, Remote-Address or X-Real-IP header (in that order of priority).
Converts responses with an empty entity into (empty) rejections.
Converts responses with an empty entity into (empty) rejections. This way you can, for example, have the marshalling of a None option be treated as if the request could not be matched.
Rejects if the request entity is non-empty.
Rejects with a RequestEntityExpectedRejection if the request entity is empty.
Rejects with a RequestEntityExpectedRejection if the request entity is empty. Non-empty requests are passed on unchanged to the inner route.
Inspects the request's Accept-Language header and determines,
which of the given language alternatives is preferred by the client.

(See http://tools.ietf.org/html/rfc7231#section-5.3.5 for more details on the
negotiation logic.)
If there are several best language alternatives that the client
has equal preference for (even if this preference is zero!)
the order of the arguments is used as a tie breaker (First one wins).
Checks the given condition before running its inner route.
Checks the given condition before running its inner route. If the condition fails the route is rejected with a ValidationRejection.
Fails the stream with akka.http.scaladsl.model.EntityStreamSizeException if its request entity size exceeds given limit.
Fails the stream with akka.http.scaladsl.model.EntityStreamSizeException if its request entity size exceeds
given limit. Limit given as parameter overrides limit configured with akka.http.parsing.max-content-length.
Beware that request entity size check is executed when entity is consumed.
Disables the size limit (configured by akka.http.parsing.max-content-length by default) checking on the incoming
HttpRequest entity.

Can be useful when handling arbitrarily large data uploads in specific parts of your routes.
Usage of withoutSizeLimit is not recommended as it turns off the too large payload protection. Therefore,
we highly encourage using withSizeLimit instead, providing it with a value high enough to successfully
handle the route in need of big entities.
