Enum Payload

Source 
pub enum Payload {
    Request(Request),
    Response(Response),
}
Expand description

The data that is sent to and from setting handlers through the service MessageHub.

Variants§

§

Request(Request)

The Request payload communicates actions to be taken upon the setting. These actions can be around access (get/listen) and changes (set). Note that there is not necessarily a 1:1 relationship between Request and Response defined later. It is possible a single Request will result into multiple Response that are delivered on the same MessageHub receptor.

§

Response(Response)

The Response payload represents the result of a Request action. Note that Response is a Result; receipients should confirm whether an error was returned and if a successful result (wich is an Option) has a value.
