std::experi...ind_first_of(3)  C++ Standard Libary std::experi...ind_first_of(3)

NAME
     std::experimental::basic_string_view::find_first_of    -	 std::experimen-
     tal::basic_string_view::find_first_of

Synopsis
	constexpr size_type find_first_of(basic_string_view v,	   (1)	(library
     fundamentals
	size_type pos = 0) const noexcept;			       TS)
	constexpr  size_type find_first_of(CharT c, size_type pos = (2) (library
     fundamentals
	0) const noexcept;					       TS)
	constexpr size_type find_first_of(const CharT* s,	   (3)	(library
     fundamentals
	size_type pos, size_type count) const;			       TS)
	constexpr  size_type find_first_of(const CharT* s,	    (4) (library
     fundamentals
	size_type pos = 0) const;				       TS)

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

	1) Finds the first occurence of any of the characters of v in this view,
     starting at
	position pos.
	2) Equivalent to find_first_of(basic_string_view(&c, 1), pos).
	3) Equivalent to find_first_of(basic_string_view(s, count), pos).
	4) Equivalent to find_first_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 first occurrence of any character of the substring, or
     npos if no
	such character is found.

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