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).
• ast_fragments 🔒

Structs

• ExpansionConfig
• ImplItemTag 🔒
• Invocation
• InvocationCollector 🔒
• MacroExpander
• MethodReceiverTag 🔒
  This struct is a hack to workaround unstable of stmt_expr_attributes. It can be removed once that feature is stabilized.
• OptExprTag 🔒
• TraitItemTag 🔒

Enums

• AddSemicolon 🔒
• AstFragment
  A fragment of AST that can be produced by a single macro expansion. Can also serve as an input and intermediate result for macro expansion operations.
• AstFragmentKind
  “Discriminant” of an AST fragment.
• InvocationKind
• SupportsMacroExpansion

Traits

• InvocationCollectorNode 🔒
  A trait implemented for all AstFragment nodes and providing all pieces of functionality used by InvocationCollector.

• build_single_delegations 🔒
