to_array
###############################################################################
Interface
========================================
.. sourcecode:: c++
template<typename T, std::size_t N>
inline SPROUT_CONSTEXPR sprout::array<T, N>
to_array(T const (& arr)[N]);
Returns
========================================
| Returns the array object copied all elements from the built-in array.
Examples
========================================
.. sourcecode:: c++
#include <sprout/array.hpp>
SPROUT_STATIC_CONSTEXPR int x[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
SPROUT_STATIC_CONSTEXPR auto y = sprout::to_array(x);
static_assert(y[0] == x[0], "array y is same as built-in array x.");
Complexity
========================================
| Recursive function invocations in *O(1)* (constant) depth.
Header
========================================
| ``sprout/array/array.hpp``
| Convenience header: ``sprout/array.hpp``
