bsl::unordered_multimap::unordered_multimap

Create an unordered multimap having the same value as the specified original object by moving (in constant time) the contents of original to the new unordered multimap. Use a copy of original.hash_function() to generate hash values for the keys contained in this unordered multimap. Use a copy of original.key_eq() to verify that two keys are equivalent. The allocator associated with original is propagated for use in the newly‐created unordered multimap. original is left in a valid but unspecified state.
