A session titled "1000 ways to die in Rust FFI" at RustFest is starting in 1.5 hours, it may be relevant to our interests. RustFest sessions can be watched live at https://rome.rustfest.eu/livetime/
Presumably these will be posted later as recordings?
I saved some slides, if you're interested in those until the videos hopefully get uploaded.
Never mind, found them all here: https://media.ccc.de/v/rustfest-rome-9-one-thousand-ways-to-die-in-rust-ffi#t=4
