Trait syntax::ast_util::PostExpansionMethodUnstable

pub trait PostExpansionMethod {
    fn pe_ident(&self) -> Ident;
    fn pe_generics<'a>(&'a self) -> &'a Generics;
    fn pe_abi(&self) -> Abi;
    fn pe_explicit_self<'a>(&'a self) -> &'a ExplicitSelf;

Macro invocations are guaranteed not to occur after expansion is complete. Extracting fields of a method requires a dynamic check to make sure that it's not a macro invocation. This check is guaranteed to succeed, assuming that the invocations are indeed gone.
