std::hive<T,Allocator>::assign_range
From cppreference.com
template< /*container-compatible-range*/<T> R >
void assign_range( R&& rg );
|
(since C++26) | |
Replaces elements in the container with a copy of each element in rg.
All iterators 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 modeled. Otherwise, the program is ill-formed.
| ||
-T must be EmplaceConstructible into the container from *ranges::begin(rg). Otherwise, the behavior is undefined.
| ||
Example
Run this code
#include <algorithm>
#include <cassert>
#include <hive>
#include <list>
int main()
{
const auto source = std::list{2, 7, 1};
auto destination = std::hive{3, 1, 4};
destination.assign_range(source);
assert(std::ranges::equal(source, destination));
}
