tt::is_std_array_of_size< N, T > Struct Template Reference

Check if type T is a std::array of a given size. More...

#include <IsStdArrayOfSize.hpp>

Detailed Description

template<size_t N, typename T>
struct tt::is_std_array_of_size< N, T >

Check if type T is a std::array of a given size.

Details

Given a size_t N and type T derives from std::true_type if T is a std::array of size N and from std::false_type otherwise.

Usage

For any type T

using result = tt::is_std_array_of_size<N, T>;

Returns: std::bool_constant

Semantics: If T is a std::array of size N then

typename result::type = std::bool_constant<true>;

otherwise

typename result::type = std::bool_constant<false>;

Example

static_assert(tt::is_std_array_of_size<3, std::array<double, 3>>::value,
              "Failed testing type trait is_std_array_of_size");
static_assert(tt::is_std_array_of_size_t<3, std::array<double, 3>>::value,
              "Failed testing type trait is_std_array_of_size");
static_assert(tt::is_std_array_of_size_v<3, std::array<double, 3>>,
              "Failed testing type trait is_std_array_of_size");
static_assert(not tt::is_std_array_of_size<3, double>::value,
              "Failed testing type trait is_std_array_of_size");
static_assert(not tt::is_std_array_of_size<2, std::array<double, 3>>::value,
              "Failed testing type trait is_std_array_of_size");
static_assert(tt::is_std_array_of_size<10, std::array<D, 10>>::value,
              "Failed testing type trait is_std_array_of_size");
