##### basic_static_string::rfind (1 of 5 overloads)

Find the last occurrence of a string within the string.

###### Synopsis

    template<
        typename T>
    constexpr basic_static_string::size_type
    rfind(
        const T& t,
        basic_static_string::size_type pos = basic_static_string::npos) const noexcept(detail::is_nothrow_convertible< const T &, string_view_type >::value);

###### Description

Constructs a temporary `string_view_type` object `sv` from `t`, and finds the last occurrence of `sv` within the string starting before or at the index `pos`.

###### Complexity

Linear.

###### Template Parameters

Type | Description
--- | ---
`T` | The type of the object to convert.

###### Constraints

`std::is_convertible<const T&, string_view>::value && !stdis_convertible<const T&, const CharT*>::value && !stdis_convertible<const T&, const basic_static_string&>::value`.

###### Return Value

The highest index `idx` less than or equal to `pos` where each element of `{sv.begin(), sv.end())` is equal to that of `{begin() + idx, begin() + idx + count)` if one exists, and `npos` otherwise.

###### Parameters

Name | Description
--- | ---
`t` | The string to search for.
`pos` | The index to start searching at. The default argument for this parameter is `npos`.
