### Class template `elements_of` <a id="range.elementsof">[[range.elementsof]]</a>
|
| 2 |
+
|
| 3 |
+
Specializations of `elements_of` encapsulate a range and act as a tag in
|
| 4 |
+
overload sets to disambiguate when a range should be treated as a
|
| 5 |
+
sequence rather than a single value.

[*Example 1*:
|
| 8 |
+
|
| 9 |
+
``` cpp
|
| 10 |
+
template<bool YieldElements>
|
| 11 |
+
generator<any> f(ranges::input_range auto&& r) {
|
| 12 |
+
if constexpr (YieldElements)
|
| 13 |
+
co_yield ranges::elements_of(r); // yield each element of r
|
| 14 |
+
else
|
| 15 |
+
co_yield r; // yield r as a single value
|
| 16 |
+
}
|
| 17 |
+
```
