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.
