(1)
(since C++11)
std::basic_stringbuf & operator=( const std::basic_stringbuf & rhs ) = delete;
(2)
1) Move assignment operator: Moves the contents of rhs into *this. After the move, *this has the associated string, the open mode, the locale, and all other state formerly held by rhs. The six pointers of std::basic_streambuf in *this are guaranteed to be different from the corresponding pointers in the moved-from rhs unless null.

[edit] Example
Run this code
#include <iostream> #include <sstream> #include <string> int main() { std::istringstream one("one"); std::ostringstream two("two"); std::cout << "Before move, one = \"" << one.str() << '"' << " two = \"" << two.str() << "\"\n"; *one.rdbuf() = std::move(*two.rdbuf()); std::cout << "After move, one = \"" << one.str() << '"' << " two = \"" << two.str() << "\"\n"; }
Output:
Before move, one = "one" two = "two" After move, one = "two" two = ""
