Module specialization_graph

Structs

• Ancestors
• Children
  Children of a given impl, grouped into blanket/non-blanket varieties as is done in TraitDef.
• FutureCompatOverlapError
• Graph
  A per-trait graph of impls in specialization order. At the moment, this graph forms a tree rooted with the trait itself, with all other nodes representing impls, and parent-child relationships representing specializations.
• LeafDef
  Information about the most specialized definition of an associated item.

Enums

• FutureCompatOverlapErrorKind
• Node
  A node in the specialization graph is either an impl or a trait definition; either can serve as a source of item definitions. There is always exactly one trait definition node: the root.
• OverlapMode
  What kind of overlap check are we doing – this exists just for testing and feature-gating purposes.

Traits

• GraphExt

Functions

• ancestors
  Walk up the specialization ancestors of a given impl, starting with that impl itself.
