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

Finds the last substring equal to the given character sequence.

1) Finds the last occurence of v in this view, starting at position pos.
2) Equivalent to rfind(basic_string_view(&c, 1), pos).
3) Equivalent to rfind(basic_string_view(s, count), pos).
4) Equivalent to rfind(basic_string_view(s), pos).

Parameters

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


Return value

Position of the first character of the found substring or npos if no such substring is found.

Complexity

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