tt::is_iterable< T> Struct Template Reference

Check if type T has a begin() and end() function. More...

#include <IsIterable.hpp>

Detailed Description

template<typename T, typename = std::void_t<>>
struct tt::is_iterable< T, typename >

Check if type T has a begin() and end() function.

Details

Given a type T inherits from std::true_type if T has member functions begin() and end(), otherwise inherits from std::false_type

Usage

For any type T

using result = tt::is_iterable<T>;

Returns: std::bool_constant

Semantics: If T has member function begin() and end() then

typename result::type = std::true_type;

otherwise

typename result::type = std::false_type;

Example

static_assert(tt::is_iterable<std::vector<double>>::value,
              "Failed testing type trait is_iterable");
static_assert(tt::is_iterable_t<std::vector<double>>::value,
              "Failed testing type trait is_iterable");
static_assert(tt::is_iterable_v<std::vector<double>>,
              "Failed testing type trait is_iterable");
static_assert(not tt::is_iterable<double>::value,
              "Failed testing type trait is_iterable");

Template Parameters

T	the type to check
