Expand description

The result of attempting to insert an impl into a group of children.

Variants

BecameNewSibling(Option<FutureCompatOverlapError>)

The impl was inserted as a new child in this group of children.

ReplaceChildren(Vec<DefId>)

The impl should replace existing impls [X1, ..], because the impl specializes X1, X2, etc.

ShouldRecurseOn(DefId)

The impl is a specialization of an existing child.
