views​::​all returns a view that includes all elements of its range argument.

2

#

The name views​::​all denotes a range adaptor object ([range.adaptor.object]).

Given a subexpression E, the expressionviews​::​all(E) is expression-equivalent to:

• (2.1)

  decay-copy(E) if the decayed type of E models view.

• (2.2)

  Otherwise, ref_view{E} if that expression is well-formed.

• (2.3)

  Otherwise, owning_view{E}.
