friend constexpr auto iter_move( const /*iterator*/ & i ) noexcept ( /* see below */ )
(since C++23)

Let current_ be the underlying iterator, pos_ be the underlying index, and Base

Equivalent to: 

template<class D, class B>
using tuple = std::tuple<D, ranges::range_rvalue_reference_t<B>>;
 
return tuple<difference_type, Base>(i.pos_, ranges::iter_move(i.current_));

This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when enumerate_view::iterator<Const>

Parameters

i - iterator

Return value

A tuple that contains an index and the result of applying ranges::iter_move

Exceptions

noexcept specification:  
noexcept (

noexcept ( ranges::iter_move (i.current_ ) ) and
std::is_nothrow_move_constructible_v <
ranges::range_rvalue_reference_t <Base>>

)
