Fields§

§expr_map: FxHashMap<ExprSource, ExprOrPatIdPacked>§expr_map_back: ArenaMap<ExprId, ExprOrPatSource>§pat_map: FxHashMap<PatSource, ExprOrPatIdPacked>§pat_map_back: ArenaMap<PatId, ExprOrPatSource>§label_map: FxHashMap<LabelSource, LabelId>§label_map_back: ArenaMap<LabelId, LabelSource>§binding_definitions: ArenaMap<BindingId, SmallVec<[PatId; 4]>>§field_map_back: FxHashMap<ExprId, FieldSource>

We don’t create explicit nodes for record fields (S { record_field: 92 }). Instead, we use id of expression (92) to identify the field.

§pat_field_map_back: FxHashMap<PatId, PatFieldSource>§template_map: Option<Box<FormatTemplate>>§expansions: FxHashMap<InFile<MacroCallPtr>, MacroCallId>§diagnostics: ThinVec<ExpressionStoreDiagnostics>

Diagnostics accumulated during lowering. These contain AstPtrs and so are stored in the source map (since they’re just as volatile).
