> In general, IndexMap::Inverse doesn’t guarantee to generate the inverse map even if the index map is (theoretically) bijective because the underlying DetectIterMap can only handle limited cases. In principle, this should have been handled by the check on the return value of `DetectIterMap`. However, because trivial iterators were removed, the check for `DetectIterMap` returning a non-empty vector wasn't sufficient to know that all iterators were present. > Is there any chance we can use it in NonSurjectiveMap? Possibly, though I think that's unrelated to the current bug. That said, I think its use will come along for free when merging the implementations of `Inverse` and `NonSurjectiveInverse`. -- This is an automated message from the Apache Git Service.
