std::ranges::zip_transform_view<F,Views...>::iterator<Const>::operator*

constexpr decltype(auto) operator*() const
    noexcept(/* see description */);

Returns the transformed element obtained by application of the invocable object of type F to the underlying poined-to elements.

Equivalent to.

return
    std::apply
    (
        [&](auto const&... iters) -> decltype(auto)
        {
            return std::invoke(*parent_->fun_, *iters...);
        },
        inner_.current_
    );

where *parent_->fun_ is the transformation function stored in the parent ranges::zip_transform_view, and current_ is the underlying tuple of iterators into Views....

Parameters

(none).

Return value

The element which is the result of transformation (mapping).

Exceptions

Notes

operator-> is not provided.

The behavior is undefined if the parent_ pointer to parent ranges::zip_transform_view is null (e.g. if *this is default constructed).
