 Public member functions

 Private member functions
 Non-member functions
(until C++20)
bool is_equal( const memory_resource& other ) const noexcept;
 
 (since C++17) 
Compares *this for equality with other. Two memory_resources compare equal if and only if memory allocated from one memory_resource can be deallocated from the other and vice versa.
Equivalent to return do_is_equal(other);.
