Trait Map

pub trait Map: Reflect {
    // Required methods
    fn get(&self, key: &dyn Reflect) -> Option<&dyn Reflect>;
    fn get_mut(&mut self, key: &dyn Reflect) -> Option<&mut dyn Reflect>;
    fn insert(
        &mut self,
        key: &dyn Reflect,
        value: &dyn Reflect,
    ) -> Option<Box<dyn Reflect>>;
    fn remove(&mut self, key: &dyn Reflect) -> Option<Box<dyn Reflect>>;
    fn len(&self) -> usize;
    fn is_empty(&self) -> bool;
    fn iter(&self) -> Iter<'_>;
    fn iter_mut(&mut self) -> PairIterMut<'_, dyn Reflect>;
}

A reflected map type.

Note this is only implemented for BTreeMap and not HashMap due to technical limitations.
