Deduction guides(C++17)

 

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

Inserts copies of elements in rg before end() in non-reversing order. Each iterator in the range rg is dereferenced exactly once.

Parameters

rg	-	a container compatible range, that is, an input_range whose elements are convertible to T.
Type requirements
- T must be EmplaceConstructible into list from *ranges::begin(rg). Otherwise, the behavior is undefined.

Return value

(none)

Complexity

Linear in size of rg.

Example

Run this code

#include <algorithm>
#include <cassert>
#include <list>
#include <vector>
 
int main()
{
    auto head = std::list{1, 2, 3, 4};
    const auto tail = std::vector{-5, -6, -7};
    head.append_range(tail);
    assert(std::ranges::equal(head, std::list{1, 2, 3, 4, -5, -6, -7}));
}
