                    |   void swap( basic_spanbuf& rhs );  | 
(since C++23) | |
Swaps the state of *this and rhs.
Calls std::basic_streambuf<Char, Traits>::swap(rhs), swaps the open mode of *this and rhs, and then makes them use the underlying buffer of each other.
Parameters
| rhs | - |  another basic_stringbuf
 | 
Return value
(none)
Exceptions
May throw implementation-defined exceptions.
Notes
This function is called automatically when swapping stream objects, it is rarely necessary to call it directly.
