operator==,!=(std::experimental::pmr::polymorphic_allocator)

template< class T1, class T2 > bool operator==( const polymorphic_allocator<T1>& lhs, const polymorphic_allocator<T2>& rhs );
template< class T1, class T2 > bool operator!=( const polymorphic_allocator<T1>& lhs, const polymorphic_allocator<T2>& rhs );

Compares two polymorphic allocators. Two polymorphic allocators compare equal if their underlying memory resource compares equal.

1) Returns *lhs.resource() == *rhs.resource()

2) Returns !(lhs == rhs)

lhs, rhs

-

polymorphic allocators to compare

1) *lhs.resource() == *rhs.resource()

2) !(lhs == rhs)
