How to parse entire crate with proc macros?

Hi everyone,
I want to conduct inventory of my crate code using proc macros and build a dependency tree between structs. I learned that a cargo sub-command and a standalone binary are the same thing, so the only question is how to point it at a crate and make it parse the code?

I only found this analyzer that shows assembly code.

Proc macros are very different to cargo commands and binaries, in particular I don't think proc macros can process entire crates, only sub-module constructs. If you're just looking to parse Rust code, have a look at Syn — Rust proc macro helper // If you need this to happen when your crate is build you can write a script.

Thanks! I've actually came across syn earlier, it's in some proc macro recipies too, IIRC.
