Update tests to use new proc-macro header 2024-11-24 17:37:25 -08:00			`//@ proc-macro: derive-b.rs`
Allow proc_macro functions to whitelist specific attributes By using a second attribute `attributes(Bar)` on proc_macro_derive, whitelist any attributes with the name `Bar` in the deriving item. This allows a proc_macro function to use custom attribtues without a custom attribute error or unused attribute lint. 2016-11-08 21:45:02 +10:30
