pub fn compare_versions(a: &str, b: &str) -> Option<Ordering>Expand description
Orders two version strings the way Eagle’s version check does: an
optional leading v, dot-separated numbers (missing ones count as 0),
then an optional -prerelease that sorts before the release itself
(its dot-separated parts compare as numbers when both are numeric, else
as text, and fewer parts sort first). +build is ignored. None when
either isn’t a version.
