iter_move (ranges::concat_view:: iterator )

From cppreference.com
Ranges library
Range adaptors
friend constexpr decltype ( auto )
iter_move ( const /*iterator*/ & it ) noexcept ( /* see description */ ) ;
(since C++26)

Returns the result of applying ranges::iter_move to the underlying iterator contained in it_ .

Let Ref be concat-rvalue-reference-t  < maybe-const  < Const, Views > ... > . Equivalent to return std:: visit ( [ ] ( const auto & i ) - > Ref { return ranges:: iter_move ( i ) ; } , it. it_  ) ; .

If it. it_ . valueless_by_exception ( ) is true , the behavior is undefined.

This function is not visible to ordinary unqualified or qualified lookup , and can only be found by argument-dependent lookup when concat_view :: iterator  < Const > is an associated class of the arguments.

Parameters

it - iterator

Return value

The result of applying ranges::iter_move to the underlying iterator.

Exceptions
