Detailed Description

Type used to represent an observer.

Every observer has an representation structure containing the relevant information. An observer is a code portion interested in some channel. The observer can be notified synchronously or asynchronously and it is called listener and subscriber respectively. The observer can be enabled or disabled during runtime by changing the enabled boolean field of the structure. The listeners have a callback function that is executed by the bus with the index of the changed channel as argument when the notification is sent. The subscribers have a message queue where the bus enqueues the index of the changed channel when a notification is sent.

See also: zbus_obs_set_enable function to properly change the observer's enabled field.
