Returns:;; The number of elements erased. Throws:;; Only throws an exception if it is thrown by `hasher` or `key_equal`. Notes:;; The `template<class K>` overload only participates in overload resolution if `Hash::is_transparent` and `Pred::is_transparent` are valid member typedefs and neither `iterator` nor `const_iterator` are implicitly convertible from `K`. The library assumes that `Hash` is callable with both `K` and `Key` and that `Pred` is transparent. This enables heterogeneous lookup which avoids the cost of instantiating an instance of the `Key` type.

Returns:;; A `node_type` owning the element if found, otherwise an empty `node_type`. Throws:;; Only throws an exception if it is thrown by `hasher` or `key_equal`.

Inserts an element constructed from `std::forward<K>(k)` in the container if and only if there is no element in the container with an equivalent key, and then invokes `f1` with a const reference to the newly created element. Otherwise, invokes `f2` with a const reference to the equivalent element.

Requires:;; `this\->get_allocator() == source.get_allocator()`. Notes:;; Invalidates iterators to the elements transferred. If the resulting size of `*this` is greater than its original maximum load, invalidates all iterators associated to `*this`.

Returns:;; A range containing all elements with key equivalent to `k`. If the container doesn't contain any such elements, returns `std::make_pair(b.end(), b.end())`.
