ok but HOW ABOUT INSTEAD OF "IGNORING IT", YOU INSTEAD TELL ME HOW TO USE IT??
Screenshot of a Rust documentation Example box, with a purple left border and a purple play-circle icon. The text reads: "This declares a helper attribute and then ignores it." Below it is a code block: #[proc_macro_derive(WithHelperAttr, attributes(helper))] pub fn derive_with_helper_attr(_item: TokenStream) -> TokenStream { TokenStream::new() }. Under it, the text reads: "To use it, we might write:" followed by a second code block: #[derive(WithHelperAttr)] struct Struct { #[helper] field: (), }

@star it will just be part of the item tokenstream. parsing the stream is a pain in the ass tho, if you wanna avoid the syn guy, then your best bet is unsynn but it's a bit verbose cus you basically have to declare a struct parser yourself

@headcr4sh I am only avoiding syn because I refuse to add the compile time equivalent of 200 tonnes to a crate for something I can do in like 20 lines!
