Deduce the template parameter KEY from the value_type of the iterators supplied to the constructor of unordered_set. This deduction guide does not participate unless the supplied allocator meets the requirements of a standard allocator.

Synopsis

Declared in <bslstl_unorderedset.h>

template<
    class INPUT_ITERATOR,
    class ALLOCATOR,
    class KEY = BloombergLP::bslstl::IteratorUtil::IterVal_t<INPUT_ITERATOR>>
requires bsl::IsStdAllocator_v<ALLOCATOR>
unordered_set<KEY, bsl::hash<KEY>, bsl::equal_to<KEY>, ALLOCATOR>(
    INPUT_ITERATOR,
    INPUT_ITERATOR,
    bsl::allocator_traits<ALLOCATOR>::size_type,
    ALLOCATOR) → unordered_set<KEY, bsl::hash<KEY>, bsl::equal_to<KEY>, ALLOCATOR>;
