Here's a working implementation of that approach: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=b9b5b874c6f4c93d6d82c1bed4e6451e. If you did want to allow unknown fields in `ExtendedFoo`, we'd codegen the extra `Ignored` variant for `ExtendedFooFields` and return that instead...

It's a bit awkward since inifinity and -infinity also go to null :( Yay JSON

Seems like an easy route would be `#[serde(default_value = "0.1")]`. It's a bit more wordy but would allow us to get the functionality out there, and we can always deprecate...

It doesn't really seem all that worth it to me to spend time worrying about how to inline a function that is called at most one time in the entire...

> `fsize` would be like `isize` but for floats. Basically, use the version that's most efficient for your processor. `isize` is not the integer type that's most efficient for your...

What kind of sandbox? What would it disallow? How would buildscripts that need extra permissions ask for them?

Rustdoc's handling of deprecated items definitely needs some improvement - see rust-lang/rust#15468 for some discussion.

Yep, I think that makes sense.

Thanks!

Ah it looks like this happens if you fun cargo-fuzz in the fuzz subdirectory instead of the crate itself.
