Macros

assign_id 🔒

Wraps a call to walk_* / walk_flat_map_* for an AST node that supports attributes (see the Annotatable enum) This method assigns a NodeId, and sets that NodeId as our current ‘lint node id’. If a macro call is found inside this AST node, we will use this AST node’s NodeId to emit lints associated with that macro (allowing #[allow] / #[deny] to be applied close to the macro invocation).
