is that valid syntax in any context? i dont think it is

[-] Ephera@lemmy.ml 4 points 5 months ago

Pretty sure, it's not. That's why I included the error highlighting.

To make it a valid struct field, you'd need to throw in a Box+dyn:

pub pint: Box<dyn Sized>

For a function parameter, you need an impl and can't have the pub:

pint: impl Sized

Obviously, you could define your own struct or generic that also happens to be called Sized, but yeah, that's cheating.
