Hi! The slides for my talk today at RE//verse 2025 (@REverseConf), "Reconstructing Rust Types: A Practical Guide for Reverse Engineers", are now published: https://github.com/cxiao/reconstructing-rust-types-talk-re-verse-2025

It's been great to catch up with so many folks - if you're at the conference, come by and say hi!

The presentation was recorded, and the video will be published at a future date!
