pub fn flow_class(flow: Flow) -> Option<&'static str>Expand description
The class for a part’s flow, if it needs one.
None for Flow::Tight and for any tier added upstream that this crate
has not been taught, which lands as one line: the same trade
part_class’s fallback makes, and the safe direction, since a part that
grows without bound breaks the rows around it while a part that stays on one
line only looks like the old rendering. Grep this when adopting a new
makeover-layout.
