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.

Inherited from std::integral_constant

Member constants

value [static]

true (public static member constant)

Member functions

operator bool	converts the object to bool, returns value (public member function)
operator() (C++14)	returns value (public member function)

Member types

Type	Definition
value_type	bool
type	std::integral_constant<bool, value>

Example

Run this code

#include <memory>
#include <flat_set>
 
static_assert(
    std::uses_allocator<std::flat_multiset<int>, void>::value == false &&
    std::uses_allocator<std::flat_multiset<int>, std::allocator<int>>::value == true
);
 
int main() {}
