I addressed some of these points in my reply to a sibling comment: https://news.ycombinator.com/item?id=48856158 https://news.ycombinator.com/item?id=48856158 I may have been a little overly specific, since there are other issues besides cycles that also block splitting crates apart, but from what I’ve seen it’s very common for modules within a crate to have cyclic dependencies and therefore not be easily factorable into separate crates.
