std::basic_string_view::find_last_not_of

constexpr size_type find_last_not_of(basic_string_view v, size_type pos = npos) const;	(1)	(since C++17)
constexpr size_type find_last_not_of(CharT c, size_type pos = npos) const;	(2)	(since C++17)
constexpr size_type find_last_not_of(const CharT* s, size_type pos, size_type count) const;	(3)	(since C++17)

Finds the last character not equal to any of the characters in the given character sequence.

1) Finds the last character not equal to any of the characters of v in this view, starting at position pos.

2) Equivalent to find_last_not_of(basic_string_view(&c, 1), pos).

3) Equivalent to find_last_not_of(basic_string_view(s, count), pos).

4) Equivalent to find_last_not_of(basic_string_view(s), pos).

v	-	view to search for
pos	-	position at which to start the search
count	-	length of the string of characters to compare
s	-	pointer to a string of characters to compare
ch	-	character to compare

Position of the last character not equal to any of the characters in the given string, or npos if no such character is found.

1-2)

noexcept specification:

noexcept

O(size() * v.size()) at worst.

find	find characters in the view (public member function)
rfind	find the last occurrence of a substring (public member function)
find_first_of	find first occurrence of characters (public member function)
find_last_of	find last occurrence of characters (public member function)
find_first_not_of	find first absence of characters (public member function)
