|
(1) | (since C++23) |

(2) | (since C++23) |
Returns an iterator to the first element of the adjacent_transform_view.
Let inner_ be the underlying ranges::adjacent_view.
1) Equivalent to
return /*iterator*/<false>(*this, inner_.begin());.
2) Equivalent to
return /*iterator*/<true>(*this, inner_.begin());.
Parameters
(none)
Return value
Iterator to the first element.
Example
#include <ranges>
int main()
{
auto sum = [](auto... args) { return (... + args); };
constexpr auto view = std::views::iota(13, 1337)
| std::views::adjacent_transform<3>(sum);
static_assert(*view.begin() == 42 and 42 == 13 + 14 + 15);
