Required methods

fn def_key(&mut self, id: DefId) -> DefKey

fn item_generics_num_lifetimes(&self, def: DefId, sess: &Session) -> usize

fn legacy_const_generic_args(&mut self, expr: &Expr) -> Option<Vec<usize>>

fn get_partial_res(&mut self, id: NodeId) -> Option<PartialRes>

Obtains resolution for a NodeId with a single resolution.

fn get_import_res(&mut self, id: NodeId) -> PerNS<Option<Res<NodeId>>>

Obtains per-namespace resolutions for use statement with the given NodeId.

fn get_label_res(&mut self, id: NodeId) -> Option<NodeId>

Obtains resolution for a label with the given NodeId.

fn definitions(&mut self) -> &mut Definitions

We must keep the set of definitions up to date as we add nodes that weren’t in the AST. This should only return None during testing.

fn lint_buffer(&mut self) -> &mut LintBuffer

fn next_node_id(&mut self) -> NodeId

fn trait_map(&self) -> &NodeMap<Vec<TraitCandidate>>

fn opt_local_def_id(&self, node: NodeId) -> Option<LocalDefId>

fn local_def_id(&self, node: NodeId) -> LocalDefId

fn create_def(
    &mut self,
    parent: LocalDefId,
    node_id: NodeId,
    data: DefPathData,
    expn_id: ExpnId,
    span: Span
) -> LocalDefId
