Un std::set è un contenitore associativo che mantiene un insieme ordinato di oggetti unici di tipo Key. L'ordinamento viene gestito dalla funzione Compare. Le operazioni di ricerca, rimozione ed inserimento hanno complessità logaritimica. I Set sono generalmente implementati come alberi red-black.

std::set soddisfa i requisiti di Container, AllocatorAwareContainer, AssociativeContainer e ReversibleContainer.
