basic_format_context& operator=(basic_format_context&& rhs);
Move assigns rhs's output
string to *this
output string. *this
will have the same format options and error state than rhs.
rhs is left in a valid
but unspecified state.
Basic guarantee: exceptions thrown by move-constructing OutputString
are propagated.
