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 and ALLOCATOR from the other parameters supplied to the constructor of unordered_multimap. This deduction guide does not participate unless the supplied HASH is invokable with a KEY, and the supplied allocator meets the requirements of a standard allocator.

Synopsis

Declared in <bslstl_unorderedmultimap.h>

    bsl::allocator_traits<ALLOCATOR>::size_type,
    HASH,
