The wrapper will handle all serialization and de-seralization of the request and response,
and furthermore provides reuse of the structs used for the request and response.

Note that Responses sent for serialization are automatically reused for similar requests.
If the response contains shared data it will cause issues, since each unique response is reused.
To disable this behavior, use `(SingleHandler).WithSharedResponse()` to disable it.
