Multiple field struct encoding which has boolean struct

[ashWhiteHat]

We would like to implement CompactAs for the struct like following.

pub struct JubjubAffine {
    x: Fp,
    y: Fp,
    is_infinity: bool,
}

Fp is the struct and already implemented CompactAs.
It seems boolean is not supported.

We found the single field struct encoding.
https://github.com/paritytech/parity-scale-codec/blob/master/tests/single_field_struct_encoding.rs
Do we have the multiple field struct encoding?
Or we can't support CompactAs for multiple fields struct?

I would appreciate it if you could response.
Thank you!

We don't support multi field compaction.
