pub fn pattern_line(
engine: &EngineState,
seed: &str,
instance: Option<&(String, String, i64)>,
) -> Option<String>Expand description
What a Pattern Component makes of replacing seed: opened on one of its
instances (instance: the instance id, its pattern and number), why the
chooser shows the seed; else how many instances follow it. None when no
pattern is seeded by it.
