std::ranges::view_interface
| Member functions | ||||
|
cbegin (C++23) |
||||
|
(C++23)
|
||||
constexpr auto cbegin(); |
(1) | (since C++23) |
|
constexpr
auto cbegin(
)
const requires ranges::range
<
const D>
;
|
(2) | (since C++23) |
The default implementation of cbegin() member function returns a constant beginning iterator of the range.
1) Let derived be a reference bound to
static_cast
<D&
>
(
*this)
Equivalent to
return
ranges::cbegin
(derived)
;
2) Same as (1), except that derived is
static_cast
<
const D&
>
(
*this)
Parameters
(none)
Return value
A constant beginning iterator of the range.
Notes
All range adaptors and range factories in the standard library and std::ranges::subrange use the default implementation of cbegin.
