Over the past few months, I went down the rabbit hole (hah) of the Uxn + Varvara computer, and have re-emerged with an emulator!

It's fast, written in safe Rust, and runs both natively and in the browser:

Hah, it looks like we saw at least two cases where ssmarshal would serialize *less* data than size_of::<T>(), due to missing padding:

github.com/oxidecompute...
github.com/oxidecompute...

(which would then trip an assertion, because we expected the exact amount of data)

...and then it turned out there were a bunch of exceptions to that rule which would fail at runtime (rather than compile-time), so Cliff went off and wrote Hubpack.

IIRC it was because ssmarshal had the property that serializing T would always fit into a buffer of size_of::<T>(), so we could do fixed-size buffers for IPC stubs.

Hubpack is the latest. IIRC at the time of its development (2+ years ago), we did some fuzzing and found that Postcard could panic on untrusted input.

It also lets you #[derive(SerializedSize)], so you can make statically sized buffers and know that your serialization won't overflow.
