Defined in header <string_view>
template< class CharT, class Traits = std::char_traits<CharT> > class basic_string_view;		(since C++17)

The class template basic_string_view describes an object that can refer to a constant contiguous sequence of CharT with the first element of the sequence at position zero.

For a basic_string_view str, pointers, iterators, and references to elements of str are invalidated when an operation invalidates a pointer in the range [str.data(), str.data() + str.size()).

Every specialization of std::basic_string_view is a TriviallyCopyable type.

(since C++23)

Several typedefs for common character types are provided:
