pub fn tiling_order(tiling: &str) -> Option<u32>Expand description
Map a tiling name to its star order n. Accepts a few named/numeric
regular tilings (the v1 set); returns None for anything else so the loader
can reject it.
none is not answered here: it selects no interlace at all, and this
function’s answer is an order. The loader takes that case before asking.
