Trait nuts::Activity [−][src]
Activities are at the core of Nuts.
From the globally managed data, they represent the active part, i.e. they can have event listeners.
The passive counter-part is defined by DomainState.
Every struct that has a type with static lifetime (anything that has no lifetime parameter that is determined only at runtime) can be used as an Activity.
You don’t have to implement the Activity trait yourself, it will always be automatically derived if possible.
To create an activity, simply register the object that should be used as activity, using nuts::new_activity or one of its variants.
It is important to understand that Activities are uniquely defined by their type. You cannot create two activities from the same type. (But you can, for example, create a wrapper type around it.) This allows activities to be referenced by their type, which mus be know at run-time. reference by their type
