I'm new to Rust and I'm fascinated by the macro system. I'm following the proc-macro-workshop from dtolnay (https://github.com/dtolnay/proc-macro-workshop).
My problem is I'm trying to use cargo expand to expand the macro in one of the specific tests but I'm struggling with the exact syntax. I understand the general format to do a single expansion is;
$ cargo expand --test test_something
but I'm not sure what to replace "test_something" with.
any help gratefully received.
