Is std::span a view?

My speculation stems from the fact that it does not "own".

I have read that it is a reference to ranges here and that it "just wraps" I have not seen anywhere been stated explicitly that it is a view.

    It probably can be considered as a view since it's just a *pointer* + a *size*. Although it allows you to modify the source. So it's not exactly similar to e.g. `string_view`. – digito_evo Jan 13 '22 at 20:59

    I am not an expert in this terminology, but it has been shared in respectable circles that "a view can not modify". For some definition of "view". – Drew Dormann Jan 13 '22 at 21:06

Generally span is a reference-like class type.

As for "view": is this related to what you're asking? (source)

template<class T, std::size_t Extent> inline constexpr bool
ranges::enable_view<std::span<T, Extent>> = true;

This specialization of ranges::enable_view makes span satisfy view.
