Struct ScopeReducer 

pub struct ScopeReducer<R, PS: 'static, PA: 'static, CS: 'static, CA: 'static, AK, SK>
where
    AK: Clone + 'static,
    SK: RefKpTrait<PS, CS>,
{
    pub state_kp: SK,
    pub action_kp: AK,
    pub cancel_id: EffectId,
    pub child: R,
    /* private fields */
}

Focuses nested state/action and runs a child reducer (UDF Scope).

Fields
