Required Methods

fn insert_blindly(&mut self, tcx: TyCtxt<'tcx>, impl_def_id: DefId)

Insert an impl into this set of children without comparing to any existing impls.

fn remove_existing(&mut self, tcx: TyCtxt<'tcx>, impl_def_id: DefId)

Removes an impl from this set of children. Used when replacing an impl with a parent. The impl must be present in the list of children already.

fn insert( &mut self, tcx: TyCtxt<'tcx>, impl_def_id: DefId, simplified_self: Option<SimplifiedType>, overlap_mode: OverlapMode, ) -> Result<Inserted<'tcx>, OverlapError<'tcx>>

Attempt to insert an impl into this set of children, while comparing for specialization relationships.
