std::list<T,Allocator>::append_range
From cppreference.com
| 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})); }
