Package frame

The frame package is responsible for the manipulation of the HTTP control headers that the Microbus framework is adding to the messages that travel over the messaging bus. It defines constants for the various Microbus- header names and type-safe getters and setters.

A frame.Frame is first created Of an *http.Request, *http.Response, http.ResponseWriter, http.Header or context.Context.

For example:

func Foo(w http.ResponseWriter, r *http.Request) error {
	callerHost := frame.Of(r).FromHost() // equivalent to r.Header.Get(frame.HeaderFromHost)
	callerID := frame.Of(r).FromID()     // equivalent to r.Header.Get(frame.HeaderFromId)
}
