enumerate_view ( ) requires std:: default_initializable < V > = default ;	(1)	(seit C++23)
constexpr explicit enumerate_view ( V base ) ;	(2)	(seit C++23)

Konstruiert eine enumerate_view .

1) Standardkonstruktor. Wertinitialisiert die zugrundeliegende Ansicht


         
          base_

. Nach der Konstruktion gibt


         base()

eine Kopie von V ( ) zurück.

2) Initialisiert die zugrundeliegende Ansicht


         
          base_

mit std :: move ( base ) .

Parameter

base

die zugrunde liegende Ansicht
