std::basic_spanbuf<CharT,Traits>::operator=

basic_spanbuf& operator=( basic_spanbuf&& rhs );	(1)	(since C++23)
basic_spanbuf& operator( const basic_spanbuf& ) = delete;	(2)	(since C++23)

1) 移动赋值运算符。等价于 auto tmp{std::move(rhs)}; this->swap(tmp); return *this;。移动赋值后，*this 持有移动赋值前 rhs 所持有的状态。是否 rhs 在移动赋值后仍然持有底层缓冲区是实现定义的。

2) 复制赋值运算符被删除；basic_spanbuf 不是 CopyAssignable。
