protected member function
<istream> <iostream>

std::istream::operator=

copy (1)
basic_istream& operator= (const basic_istream&) = delete;
move (2)
basic_istream& operator= (basic_istream&& rhs);
Move assignment
Exchanges all internal members between rhs and *this, except the pointers to the associated stream buffers: rdbuf shall return the same in both objects as before the call.

This is the same behavior as calling member istream::swap.

Derived classes can call this function to implement move semantics.

Parameters

rhs
Another istream object.

Return Value

*this

Data races

Modifies both stream objects (*this and rhs).

Exception safety

No-throw guarantee: this member function never throws exceptions.
