std::{{{1}}}::assign_range
From cppreference.com
| template< container-compatible-range<T> R > void assign_range( R&& rg ); |
(since C++23) | |
Replaces elements in the container with a copy of each element in rg. Invalidate all references, pointers, and iterators referring to the elements of the container. Each iterator in the range rg is dereferenced exactly once.
The exposition only concept container-compatible-range is defined as below:
template<class R, class T> concept container-compatible-range = // exposition only ranges::input_range<R> && std::convertible_to<ranges::range_reference_t<R>, T>;
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 modeled. Otherwise, the program is ill-formed. | ||
-T must be EmplaceConstructible into the container from *ranges::begin(rg). Otherwise, the behavior is undefined.
