### `ranges::data` <a id="range.prim.data">[[range.prim.data]]</a>

The name `ranges::data` denotes a customization point object
|
| 4 |
+
[[customization.point.object]].
|
| 5 |
+
|
| 6 |
+
Given a subexpression `E` with type `T`, let `t` be an lvalue that
|
| 7 |
+
denotes the reified object for `E`. Then:
|
| 8 |
+
|
| 9 |
+
- If `E` is an rvalue and `enable_borrowed_range<remove_cv_t<T>>` is
|
| 10 |
+
`false`, `ranges::data(E)` is ill-formed.
|
| 11 |
+
- Otherwise, if `T` is an array type [[basic.compound]] and
|
| 12 |
+
`remove_all_extents_t<T>` is an incomplete type, `ranges::data(E)` is
|
| 13 |
+
ill-formed with no diagnostic required.
|
| 14 |
+
- Otherwise, if `decay-copy(t.data())` is a valid expression of pointer
|
| 15 |
+
to object type, `ranges::data(E)` is expression-equivalent to
|
| 16 |
+
`decay-copy(t.data())`.
|
| 17 |
+
- Otherwise, if `ranges::begin(t)` is a valid expression whose type
|
| 18 |
+
models `contiguous_iterator`, `ranges::data(E)` is
|
| 19 |
+
expression-equivalent to `to_address(ranges::begin(E))`.
|
| 20 |
+
- Otherwise, `ranges::data(E)` is ill-formed.
|
| 21 |
+
|
| 22 |
+
[*Note 1*: Diagnosable ill-formed cases above result in substitution
|
| 23 |
+
failure when `ranges::data(E)` appears in the immediate context of a
|
| 24 |
+
template instantiation. — *end note*]
|
| 25 |
+
|
| 26 |
+
[*Note 2*: Whenever `ranges::data(E)` is a valid expression, it has
|
| 27 |
+
pointer to object type. — *end note*]
