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.

Structs

AstNodeWrapper

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

AstDeref

A utility trait to reduce boilerplate. Standard Deref(Mut) cannot be reused due to coherence.

HasAttrs

HasNodeId

HasSpan

A trait for AST nodes having a span.

HasTokens
