I'm trying to create my own panic hook using the reporting mechanism from this crate but with my own error message. Something like this:

https://github.com/themaxdavitt/human-panic-metadata-poc/blob/c1ce95c11449018aa4f3bde9868a34d54798d110/wrapper/src/lib.rs#L24-L33

However, currently the metadata! macro refers to the Metadata struct without using $crate to help the compiler know where that Metadata type is defined, leading to the following error:

error[E0422]: cannot find struct, variant or union type `Metadata` in this scope
 --> user/src/bin/broken.rs:4:5
  |
4 |     wrapper::broken_custom_panic_hook!();
  |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ not found in this scope
  |

If I replace the metadata! invocation with the contents of the macro itself (using $crate to refer to the Metadata type to populate), it compiles as expected:

https://github.com/themaxdavitt/human-panic-metadata-poc/blob/c1ce95c11449018aa4f3bde9868a34d54798d110/wrapper/src/lib.rs#L7-L21

Here's the repo I created demonstrating this. Let me know if you have any questions and thanks for maintaining this crate!

EDIT: I know this is pretty minor, and can easily be fixed by just useing the type before invoking the macro, I just wanted to leave an issue about it in case someone else stumbles across this.
