From cppreference.com
 
 
 
 
Defined in header <flat_set>
template<class Key, class Compare, class KeyContainer, class Allocator >

struct uses_allocator<std::flat_multiset<Key, Compare, KeyContainer>, Allocator>

    :std::bool_constant<std::uses_allocator_v<KeyContainer, Allocator>>{};
(since C++23)

Provides a transparent specialization of the std::uses_allocator type trait for std::flat_multiset: the container adaptor uses allocator if and only if the underlying container does.
