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(std::addressof(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 |

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.
