(2) (library fundamentals TS)
template<class Allocator>
basic_string_view(const basic_string<CharT, Traits, Allocator>& str);

constexpr basic_string_view(const CharT* s, size_type count);
(4) (library fundamentals TS)
constexpr basic_string_view(const CharT* s);
(5) (library fundamentals TS)
1) Default constructor. Constructs an empty basic_string_view.
2) Copy constructor. Constructs a view of the same content of other.
3) Constructs a view of str.
4) Constructs a view of the first count characters of character string pointed to by s. s can contain null characters. The behavior is undefined if s does not point to an array of at least count elements of CharT.
5) Constructs a view of the null-terminated character string pointed to by s. The length of the view is determined by the first null character. The behavior is undefined if s does not point to an array of at least Traits::length(s)+1 elements of CharT.
