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
