std::deque::assign_range(3)   C++ Standard Libary  std::deque::assign_range(3)

NAME
       std::deque::assign_range	- std::deque::assign_range

Synopsis
	  template< container-compatible-range<T> R >  (since C++23)
	  void assign_range( R&& rg );

	  Replaces  elements  in  the container	with a copy of each element in
       rg.

	  All iterators	(including the end() iterator) and all	references  to
       the elements are
	  invalidated.

	  Each iterator	in the range rg	is dereferenced	exactly	once.

	  The behavior is undefined if rg overlaps with	the container.

Parameters
	  rg	    -	     an	input_range with reference type	convertible to
       the element type
			   of the container

Type requirements
	  -
	  std::assignable_from<T&, ranges::range_reference_t<R>> must be  mod-
       eled. Otherwise,
	  the program is ill-formed.
	  -
	  T  must be EmplaceConstructible into the container from *ranges::be-
       gin(rg).
	  Otherwise, the behavior is undefined.

Return value
	  (none)

Example
       // Run this code

	#include <algorithm>
	#include <cassert>
	#include <deque>
	#include <list>

	int main()
	{
	    const auto source =	std::list{2, 7,	1};
	    auto destination = std::deque{3, 1,	4};
	#ifdef __cpp_lib_containers_ranges
	    destination.assign_range(source);
	#else
	    destination.assign(source.cbegin(),	source.cend());
	#endif
	    assert(std::ranges::equal(source, destination));
	}
