tt::is_std_array< T > Struct Template Reference

Check if type T is a std::array. More...

#include <IsStdArray.hpp>

Detailed Description

template<typename T>
struct tt::is_std_array< T >

Check if type T is a std::array.

Details

Given a type T derives from std::true_type if T is a std::array and from std::false_type if T is not a std::array.

Usage

For any type T

using result = tt::is_std_array<T>;

Returns: std::bool_constant

Semantics: If T is a std::array then

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

otherwise

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

Example

static_assert(tt::is_std_array<std::array<double, 3>>::value,
              "Failed testing type trait is_std_array");
static_assert(tt::is_std_array_t<std::array<double, 3>>::value,
              "Failed testing type trait is_std_array");
static_assert(tt::is_std_array_v<std::array<double, 3>>,
              "Failed testing type trait is_std_array");
static_assert(not tt::is_std_array<double>::value,
              "Failed testing type trait is_std_array");
static_assert(tt::is_std_array<std::array<D, 10>>::value,
              "Failed testing type trait is_std_array");
