EntityCommandInsertRecursive effect

[Trouv]

Ended up needing this on a new project...

/// [`Effect`] that inserts a component recursively on relationship targets.
#[derive(Debug, Copy, Clone, PartialEq, Eq, Hash, Reflect)]
pub struct EntityCommandInsertRecursive<RT, B>
where
    RT: RelationshipTarget,
    B: Bundle + Clone,
{
    pub entity: Entity,
    pub bundle: B,
    _phantom: PhantomData<RT>,
}

impl<RT, B> EntityCommandInsertRecursive<RT, B>
where
    B: Bundle + Clone,
    RT: RelationshipTarget,
{
    /// Construct a new [`EntityCommandInsertRecursive`].
    fn new(entity: Entity, bundle: B) -> Self {
        Self {
            entity,
            bundle,
            _phantom: PhantomData,
        }
    }
}

impl<RT, B> Effect for EntityCommandInsertRecursive<RT, B>
where
    RT: RelationshipTarget,
    B: Bundle + Clone,
{
    type MutParam = Commands<'static, 'static>;

    fn affect(self, param: &mut <Self::MutParam as bevy::ecs::system::SystemParam>::Item<'_, '_>) {
        param
            .entity(self.entity)
            .insert_recursive::<RT>(self.bundle);
    }
}
