Function nuts::new_domained_activity

pub fn new_domained_activity<A, D>(activity: A, domain: &D) -> ActivityId<A> where
    A: Activity,
    D: DomainEnumeration, 

Consumes a struct that is registered as an Activity that has access to the specified domain. Use the returned ActivityId to register callbacks on the activity.

use nuts::{domain_enum, DomainEnumeration};

#[derive(Default)]

struct MyMessage;

#[derive(Clone, Copy)]
enum MyDomain {
    DomainA,
    DomainB,
}
domain_enum!(MyDomain);

// Add data to domain
nuts::store_to_domain(&MyDomain::DomainA, 42usize);

// Register activity
let activity_id = nuts::new_domained_activity(MyActivity, &MyDomain::DomainA);

// Add event listener that listens to published `MyMessage` types and has also access to the domain data
activity_id.subscribe_domained(
    |_my_activity, domain, msg: &MyMessage| {
        // borrow data from the domain
        let data = domain.try_get::<usize>();
        assert_eq!(*data.unwrap(), 42);
    }
);

// make sure the subscription closure is called
nuts::publish( MyMessage );
