Tracking issue: Unsupported serde attributes

• Feedback request: How to handle unsupported "self-describing-only" attributes serde-rs/serde#2674
• [Bug] Postcard does not handle serde attribute skip_serializing_if properly #122
• #[serde(flatten)] causes serialization to fail #29

How to handle this?

I'm going to investigate #122.

FYI I also have deserialization issues when using deserialize_with.

I made a PoC for the skipping: #174

[ManevilleF]

It seems that #[serde(skip)] breaks deserialization, due to discriminant offset

pub enum MyEnum {
    A,
    #[serde(skip)]
    B,
    C,
    D,
}

In this case deserializing A would work. But not C. postcard would attempt to deserialize C as D
