bool is_equal ( const memory_resource & other ) const noexcept ;		(seit C++17)

Vergleicht * this auf Gleichheit mit other . Zwei memory_resource s sind genau dann gleich, wenn Speicher, der von einem memory_resource allokiert wurde, vom anderen freigegeben werden kann und umgekehrt.

Entspricht return do_is_equal ( other ) ; .
