other to *this, effectively move-assigning both the std::basic_istream base class subobject and the wrapped std::basic_spanbuf.basic_ispanstream is not copy assignable.Note that move assignment operator of the base class swaps all stream state variables (except for rdbuf()) between *this and other.
It is implementation-defined whether the std::basic_spanbuf wrapped in other still holds an underlying buffer after the move assignment.
| other | - | another stream to move from |
*this.
May throw implementation-defined exceptions.

(C++23) | assigns a basic_spanbuf object (public member function of std::basic_spanbuf<CharT,Traits>) |

(C++11) | move-assigns from another basic_istream (protected member function) |
