Types

type AfterFetcher

type AfterFetcher interface {

	//AfterFetch one of the lifecycle hooks, returns bool if response was closed (i.e. response.WriteHeader())
	//or just an error if it is needed to stop the routers flow.

	AfterFetch(data interface{}, response http.ResponseWriter, request *http.Request) (responseClosed bool, err error)
