`to_array`

namespace opentl {
    template <typename T, opentl::size_t N>
    constexpr opentl::array<opentl::remove_cv_t<T>, N> to_array(T (&a)[N]);

    template <typename T, opentl::size_t N>
    constexpr opentl::array<opentl::remove_cv_t<T>, N> to_array(T (&&a)[N]);
}

Creates an array from a C-style array.

Declared in <array/to_array.hpp>.

Template Parameters

Name	Description
`T`	The element type.
`N`	The array size.

Parameters

Name	Description
`a`	The C-style array to convert.

Return Value

An opentl::array with the same elements as the source C-style array. The element type has const and volatile qualifiers removed, matching the source element type otherwise.

Overloads

Overload	Description
`to_array(T (&)[N])`	Copies elements from an l-value C-style array.
`to_array(T (&&)[N])`	Moves elements from an r-value C-style array.

Example

#include <opentl/array.hpp>
#include <array/to_array.hpp>

int main() {
    int c_arr[3] = {1, 2, 3};
    opentl::array<int, 3> arr = opentl::to_array(c_arr);

    const int const_arr[2] = {4, 5};
    opentl::array<int, 2> arr2 = opentl::to_array(const_arr);  // const removed
}
