Throws:;; Only throws an exception if it is thrown by `hasher` or `key_equal`. Notes:;; A node extracted using this method can be inserted into a compatible `unordered_multimap`. + + 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. 707/10000 · 707
