Trait MutableMap

pub trait MutableMap<K, V> {
    type UnderlyingMap: GenericMap<K, V>;

    // Required method
    fn make_mut(&mut self) -> &mut Self::UnderlyingMap;
}

A trait implemented by BTreeMap, im_rc::OrdMap and Rc<BTreeMap>.

You frequently want to clone incrementals a lot. Making it so

Required Associated Types

type UnderlyingMap: GenericMap<K, V>

Required Methods

fn make_mut(&mut self) -> &mut Self::UnderlyingMap

For Rc, this is BTreeMap.
