template<class value_t>
struct xtd::forward_iterable< value_t >

Represents the forward iterable concept.

Definition: template<class value_t>

concept xtd::forward_iterable;

xtd::forward_iterable
Definition forward_iterable.hpp:18

Examples: The following code shows how to use xtd::forward_iterable concept
#include <xtd/xtd>

auto int_generator() -> enumerable_generator<int> {

co_yield 15;

co_yield 11;

co_yield 13;

co_yield 14;

co_yield 12;

}

template <forward_iterable iterable_t>

[[nodiscard]] auto iterate(iterable_t&& iterable) -> enumerable_generator<forward_iterable_value_type<iterable_t>> {

for (const auto& item : iterable)

co_yield item;

}

auto main() -> int {

for (auto item : iterate(std::vector {5, 1, 3, 4, 2}).select([](auto v) {return v * 2;}).order())

println("{,2}", item);

for (auto item : iterate(list {10, 6, 8, 9, 7}).select([](auto v) {return v * 3;}).order())

println("{,2}", item);

for (auto item : iterate(int_generator()).select([](auto v) {return v * 4;}).order())

println("{,2}", item);

}
