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.

Parameters

other	-	another view to initialize the view with
str	-	string to initialize view with
s	-	pointer to a character string to initialize the view with
count	-	size of the resulting view

Exceptions

noexcept specification:

Complexity

1-4) constant

5) linear in length of s
