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

Compare * this pour l'égalité avec other . Deux memory_resource sont égaux si et seulement si la mémoire allouée depuis l'un memory_resource peut être désallouée depuis l'autre et vice versa.

Équivalent à return do_is_equal ( other ) ; .
