Trait snec::Receiver

pub trait Receiver<E: Entry> {
    fn receive(&mut self, new_value: &E::Data);
}

Trait for types which wish to be notified when the specified configuration table entry changes.

Several reference types and standard library types implement Receiver:

• A mutable borrow of any type can be used as a receiver

Required methods

fn receive(&mut self, new_value: &E::Data)

Receive a notification about the value of the entry changing to the specified new value.

This method shouldn't be called manually — please use EntryStorage instead, which will automatically call this method. It's a logic error to invoke this without actually setting the value to something new in the storage.
