bool operator!=( const std::pmr::polymorphic_allocator<T1>& lhs,

(until C++20)

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)

The != operator is synthesized from operator==.

 (since C++20)

Parameters

lhs, rhs - polymorphic allocators to compare

Return value

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