- assign_
id ๐ - Wraps a call to
walk_*
/walk_flat_map_*
for an AST node that supports attributes (see theAnnotatable
enum) This method assigns aNodeId
, and sets thatNodeId
as our current โlint node idโ. If a macro call is found inside this AST node, we will use this AST nodeโsNodeId
to emit lints associated with that macro (allowing#[allow]
/#[deny]
to be applied close to the macro invocation). - ast_
