How would a torus world (donut shaped) have to rotate in order to have a stable day / night cycle in all of its regions?

In this universe, mass and gravity work differently so stable torus planets are possible (donut shaped).

How would a torus world orbiting a single star have to rotate in order to have a stable day and night cycle on all of its regions? For example if it was constantly in a horizontal position from its star and rotated as such, the inside of the ring would be eternally dark. So I believe its rotation would likely have to be both horizontal, vertical and complex so that all its regions would have similar constant day and night cycles.

Assume this torus world has a total surface area similar to Earth's, a similar distance from its sun, 12 hour days and nights, etc, etc. (If that information is necessary for any reason.)
