pub struct TraitRef<'hir> {
    pub path: &'hir Path<'hir>,
    pub hir_ref_id: HirId,
}
Expand description

References to traits in impls.

resolve maps each TraitRef’s ref_id to its defining trait; that’s all that the ref_id is for. Note that ref_id’s value is not the HirId of the trait being referred to but just a unique HirId that serves as a key within the resolution map.

Fields

path: &'hir Path<'hir>hir_ref_id: HirId
