== Description

Return `true` if the specified `lhs` and `rhs` objects have the same value, and `false` otherwise. Two `unordered_multimap` objects have the same value if they have the same number of key‐value pairs, and each key‐value pair that is contained in one of the objects is also contained in the other object. This method requires that the (template parameter) types `KEY` and `VALUE` both be `equality‐comparable` (see {Requirements on `KEY` and `VALUE`}).

== Return Value

`true` if the unordered multimaps compare equal
