Trait Implementations

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

fn clone(&self) -> MultiMap<K, V>

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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

fn default() -> MultiMap<K, V>

Returns the “default value” for a type.

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

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

This method tests for self and other values to be equal, and is used by ==.
