Trait GetValue

pub trait GetValue: DefinedAt {
    type Value: Clone;

    // Required method
    fn try_get_value(&self) -> Option<Self::Value>;

    // Provided method
    fn get_value(&self) -> Self::Value { ... }
}

A variation of the Get trait that provides a signposted “always-non-reactive” API. E.g. for StoredValue.
