operator==,!=(std::scoped_allocator_adaptor)

Since C++11

template< class OuterAlloc1, class OuterAlloc2, class... InnerAllocs >
bool operator==( const scoped_allocator_adaptor<OuterAlloc1, InnerAllocs...>& lhs,
                 const scoped_allocator_adaptor<OuterAlloc2, InnerAllocs...>& rhs ) noexcept;

Since C++11, Until

template< class OuterAlloc1, class OuterAlloc2, class... InnerAllocs >
bool operator!=( const scoped_allocator_adaptor<OuterAlloc1, InnerAllocs...>& lhs,
                 const scoped_allocator_adaptor<OuterAlloc2, InnerAllocs...>& rhs ) noexcept;

Compares two scoped allocator adaptors. Two such allocators are equal if:

lhs.outer_allocator() == rhs.outer_allocator(), and if sizeof...(InnerAllocs) > 0, lhs.inner_allocator() == rhs.inner_allocator().

The != operator is synthesized from operator== (od C++20)

Parameters

lhs, rhs - scoped allocator adaptors to compare

Return value

1. Returns true if lhs and rhs are equal, false otherwise.
   
2. Returns true if lhs and rhs are not equal, false otherwise.
