This is known fallout from rust-lang/rust#65785 (comment)

Thanks for the heads up, @pnkfelix! Hopefully there's another crate I can use as a replacement. 🤞

Hey @jmacdonald : I asked alexcrichton about this last week, and they told me that you should probably switch to https://crates.io/crates/syn

(So I figure use that, or throw away the build script and figure out how to redo your use case as a proc-macro.)

Any news on this?

Working on it tonight. 😇

@pnkfelix for my use case, leaning on file names and a simple regex was enough to extract what I was after. Thanks again! 🍻
