Hello, is there a way to pass types as uuid?
UUID is generally represented as an string but it is stored as a fixed-size array of numbers in some languages such as rust.

Would there be any perf gain by passing the UUID as a tuple? Is there a way to automatically convert the tuple back to an UUID in both ends (host/guest)?

Ideally, this would not only apply to UUID but to other types that host or guest are able to de-serialize from simple types.

At present string, list, or a tuple are the main options for doing this, though they'll all require a little extra conversion on both ends. There are discussions about adding bounded strings and lists in the future, which will improve on these.

I see there is no way of avoiding an extra layer of conversion for this types. A little internal wrapper library will do the work.
Thanks.
