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

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

where INTS is the pack of integers 0, 1, ..., (sizeof...(Views)-1).

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
