constexpr size_type find_last_of(const CharT* s, size_type pos = 0) const;	(4)	(library fundamentals TS)

Finds the last character equal to any of the characters in the given character sequence.

1) Finds the last occurence of any of the characters of v in this view, starting at position pos.

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

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

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

Parameters

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

Return value

Position of the last occurrence of any character of the substring, or npos if no such character is found.

Exceptions

1-2)

noexcept specification:  

noexcept

  

Complexity

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