#### Overview <a id="range.drop.overview">[[range.drop.overview]]</a>
|
| 2 |
+
|

+
`drop_view` produces a `view` excluding the first N elements from
|
| 4 |
+
another `view`, or an empty range if the adapted `view` contains fewer
|
| 5 |
+
than N elements.
|
| 6 |
+
|
| 7 |
+
The name `views::drop` denotes a range adaptor object
|
| 8 |
+
[[range.adaptor.object]]. Let `E` and `F` be expressions, let `T` be
|
| 9 |
+
`remove_cvref_t<decltype((E))>`, and let `D` be
|
| 10 |
+
`range_difference_t<decltype((E))>`. If `decltype((F))` does not model
|
| 11 |
+
`convertible_to<D>`, `views::drop(E, F)` is ill-formed. Otherwise, the
|
| 12 |
+
expression `views::drop(E, F)` is expression-equivalent to:
|
| 13 |
+
|
| 14 |
+
- If `T` is a specialization of `ranges::empty_view`
|
| 15 |
+
[[range.empty.view]], then `((void) F, decay-copy(E))`.
|
| 16 |
+
- Otherwise, if `T` models `random_access_range` and `sized_range` and
|
| 17 |
+
is
|
| 18 |
+
- a specialization of `span` [[views.span]] where
|
| 19 |
+
`T::extent == dynamic_extent`,
|
| 20 |
+
- a specialization of `basic_string_view` [[string.view]],
|
| 21 |
+
- a specialization of `ranges::iota_view` [[range.iota.view]], or
|
| 22 |
+
- a specialization of `ranges::subrange` [[range.subrange]],
|
| 23 |
+
|
| 24 |
+
then
|
| 25 |
+
`T{ranges::begin(E) + min<D>(ranges::size(E), F), ranges::end(E)}`,
|
| 26 |
+
except that `E` is evaluated only once.
|
| 27 |
+
- Otherwise, `ranges::drop_view{E, F}`.

[*Example 1*:
|
| 30 |
+
|
| 31 |
+
``` cpp
|
| 32 |
+
auto ints = views::iota(0) | views::take(10);
|
| 33 |
+
auto latter_half = drop_view{ints, 5};
|
| 34 |
+
for (auto i : latter_half) {
|
| 35 |
+
cout << i << ' '; // prints 5 6 7 8 9
|
| 36 |
+
}
|
| 37 |
+
```
