********************
Welcome from Rust and Cpp Cardiff! All levels welcome!
********************
In previous meetups, we have been digging in to the world of rust macros. There was a lot of appetite for getting into the weeds a bit more with them, so this session we'll be looking at how to write proc macros, and using cargo expand to help figure out what they're doing.

Recordings of previous meetups are available on youtube. We also have a discord server for chatting between meetups - message any of the meetup organizers for the discord link.

Look forward to seeing you there!
