pub fn order(a: &str, b: &str) -> Option<Ordering>Expand description
How the version a of one issue stands to its version b: Greater when a is the later,
Less when it is the earlier, Equal when nothing the token covers changed between them —
and None when either is not a token of this plugin, or the two cannot both be versions of
one issue read in order.
Two versions naming different repositories are never ordered: a transfer moves the issue and says nothing about which reading came first. Both times and the relationship count only ever move forward, so a later version holds none of the three earlier or smaller; one holding one of them ahead and another behind is no version read after the other. When all three are equal and the comment counts are not, the version with fewer comments is the later: the one change that moves the comment count and nothing else is a comment deleted, because adding one moves the issue’s time.
