Enum rustc_middle::traits::specialization_graph::Node

pub enum Node {
    Impl(DefId),
    Trait(DefId),
}

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.

Variants

Impl(DefId)

Trait(DefId)

Implementations

impl<'tcx> Node

pub fn is_from_trait(&self) -> bool

pub fn items(
    &self,
    tcx: TyCtxt<'tcx>
) -> impl 'tcx + Iterator<Item = &'tcx AssocItem>

Iterate over the items defined directly by the given (impl or trait) node.

pub fn item(
    &self,
    tcx: TyCtxt<'tcx>,
    trait_item_name: Ident,
    trait_item_kind: AssocKind,
    trait_def_id: DefId
) -> Option<AssocItem>

Finds an associated item defined in this node.

If this returns None, the item can potentially still be found in parents of this node.

pub fn def_id(&self) -> DefId
