From cppreference.com
< cpp‎ | utility‎ | tuple

tuple& operator=( const tuple& other ); | (1) | (since C++11)
tuple& operator=( tuple&& other ); | (2) | (since C++11)
template< class... UTypes > tuple& operator=( const tuple<UTypes...>& other ); | (3) | (since C++11)
template< class... UTypes > tuple& operator=( tuple<UTypes...>&& other ); | (4) | (since C++11)
template< class U1, class U2 > tuple& operator=( const pair<U1,U2>& p ); | (5) | (since C++11)

Replaces the contents of the tuple with the contents of another tuple or a pair.

1) Copy assignment operator. Replaces each element with a copy of the corresponding element of `other`.

2) Move assignment operator. Replaces each element with the corresponding element of `other` using move semantics.

3) For all `i`, assigns std::get<i>(other) to std::get<i>(*this).

4) For all `i`, assigns std::forward<Ui>(std::get<i>(other)) to std::get<i>(*this).

5) Assigns p.first to the first element of *this and p.second to the second element of *this.

6) Assigns std::forward<U1>(p.first) to the first element of *this and std::forward<U2>(p.second) to the second element of *this.
