    std::scoped_allocator_adaptor
     
    Defined in header <scoped_allocator> 
    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) 
    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 C++20)

    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==.

    		(since 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.
