TraitRef in rustc_ast::ast - Rust (original) (raw)

pub struct TraitRef {
    pub path: Path,
    pub ref_id: NodeId,
}

Expand description

TraitRefs appear in impls.

Resolution maps each TraitRef’s ref_id to its defining trait; that’s all that the ref_id is for. The impl_id maps to the “self type” of this impl. If this impl is an ItemKind::Impl, the impl_id is redundant (it could be the same as the impl’s NodeId).
