Deduce the template parameters KEY and VALUE from the value_type of the initializer_list supplied to the constructor of unordered_multimap. Deduce the template parameters HASH, EQUAL and ALLOCATOR from the other parameters supplied to the constructor of unordered_multimap. This deduction guide does not participate unless the supplied allocator is convertible to bsl::allocator<bsl::pair<const KEY, VALUE>>.
