Module rustc_ast::ast_traits

A set of traits implemented for various AST nodes, typically those used in AST fragments during macro expansion. The traits are not implemented exhaustively, only when actually necessary.

Macros

• impl_has_attrs 🔒
• impl_has_attrs_none 🔒
• impl_has_node_id 🔒
• impl_has_tokens 🔒
• impl_has_tokens_none 🔒
• impl_not_ast_deref 🔒

Structs

• AstNodeWrapper
  A newtype around an AST node that implements the traits above if the node implements them.

Traits

• AstDeref
  A utility trait to reduce boilerplate. Standard Deref(Mut) cannot be reused due to coherence.
• HasAttrs
  A trait for AST nodes having (or not having) attributes.
• HasNodeId
  A trait for AST nodes having an ID.
• HasTokens
  A trait for AST nodes having (or not having) collected tokens.
