Syntax tree enum. This type is a syntax tree enum. use syn:: fold:: {self, Fold}; use syn:: parse:: {Parse, ParseStream, Result}; use syn:: punctuated:: Punctuated; use syn:: {parse_macro_input, parse_quote, Expr, Ident, ItemFn, Local, Pat, Stmt, Token}; /// Parses a list of variable names separated by commas. /// /// a, b, c /// /// This is how the compiler passes in arguments to our attribute -- it is Teams.

The result of that is a syn::Item which is an enum of all the different types of rust Items and will allow us to determine exactly what our attribute is decorating. For us, we only want this to work on functions, so we match parse2 , if it is a fn we pass the inner data off to handle_func if not, we panic with a message about only supporting fn s.

The parsing sure seems wasted, since the result is immediately converted into a tokenstream again. use syn::{Error, Ident, LitStr, Result, Token}; use syn:: parse:: ParseStream; // Parses input that looks like `name = "string"` where the key must be // the identifier `name` and the value may be any string literal. The Rust community has a very good crate, syn, for parsing TokenStream. synprovides a ready-made parser for Rust syntax that can be used to parse TokenStream.

Apologies in advance for how silly this probably is. I have some familiarity with the visitor pattern and AST parsing, but almost none with Rust.
