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

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).

[edit] 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

[edit] Return value

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

noexcept specification:

[edit] Complexity

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