Interface
|
|
========================================
|
|
.. sourcecode:: c++
|
|
|
|
SPROUT_CONSTEXPR const_iterator cbegin() const SPROUT_NOEXCEPT;
|
|
|
|
Returns
|
|
========================================
|
|
|
|
| iterator for the first element always const.
|
|
|
|
Examples
|
|
========================================
|
|
.. sourcecode:: c++
|
|
|
|
#include <sprout/string.hpp>
|
|
using namespace sprout;
|
|
|
|
SPROUT_STATIC_CONSTEXPR auto input = string<8>("homuhomu");
|
|
static_assert(*input.cbegin() == 'h', "input first element is h.");
|
|
|
|
Complexity
|
|
========================================
|
|
|
|
| Recursive function invocations in *O(1)* (constant) depth.
|
|
