If this looks a bit complex, don't worry, what the three type parameters stand for is the only thing you'll hopefully have to remember when using the API! Going one-by-one: * ``U[_]`` specifies if the request method and URL are specified. Using the API, this can be either ``type Empty[X] = None``, meaning that the request has neither a method nor an URI. Or, it can be ``type Id[X] = X`` (type-level identity), meaning that the request has both a method and an URI specified. Only requests with a specified URI & method can be sent. -* ``T`` specifies the type to which the response will be read. By default, this is ``String``. But it can also be e.g. ``Array[Byte]`` or ``Unit``, if the response should be ignored. Response body handling can be changed by calling the ``.response`` method. With backends which support streaming, this can also be a supported stream type. -* ``S`` specifies the stream type that this request uses. Most of the time this will be ``Nothing``, meaning that this request does not send a streaming body or receive a streaming response. So most of the times you can just ignore that parameter. But, if you are using a streaming backend and want to send/receive a stream, the ``.streamBody`` or ``response(asStream[S])`` will change the type parameter. +* ``T`` specifies the type to which the response will be read.
