``` cpp

+
int compare(basic_string_view<charT, traits> sv) const noexcept;
|
| 5 |
+
```
|
| 6 |
+
|
| 7 |
+
*Effects:* Determines the effective length `rlen` of the strings to
|
| 8 |
+
compare as the smaller of `size()` and `sv.size()`. The function then
|
| 9 |
+
compares the two strings by calling
|
| 10 |
+
`traits::compare(data(), sv.data(), rlen)`.
|
| 11 |
+
|
| 12 |
+
*Returns:* The nonzero result if the result of the comparison is
|
| 13 |
+
nonzero. Otherwise, returns a value as indicated in
|
| 14 |
+
Table [[tab:strings.compare]].

unless `is_convertible_v<const T&, basic_string_view<charT, traits>>` is

`true` and `is_convertible_v<const T&, const charT*>` is `false`.
