impl<K, V> PartialEq for MultiMap<K, V>
where K: Ord + PartialEq + Clone + PartialEq, V: Ord + PartialEq + Clone + PartialEq,

source§

fn eq(&self, other: &MultiMap<K, V>) -> bool

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
