Field Attributes

To ignore a field or variant, annotate it with #[serde(skip)]. This is useful when transferring partially private data because it allows you to specify which data is exposed to Dart. See Serde’s documentation on variant and field attributes for more information on how Serde handles this attribute.

Rust

#[derive(Serialize, RustSignal)]
struct UpdateMessage {
  event: String,
  struct_data: StructData,
  enum_data: EnumData,
}

#[derive(Serialize, SignalPiece)]
struct StructData {
  my_public_field: bool,
  #[serde(skip)]
  my_private_field: bool,
}

#[derive(Serialize, SignalPiece)]
enum EnumData {
  Variant1(i32, #[serde(skip)] i32),
  Variant2 {
    my_public_field: bool,
    #[serde(skip)]
    my_private_field: bool,
  },
}

Some attributes from Serde are banned at compile-time. This is because rinf gen analyzes Rust code statically by reading type annotations, and it cannot infer the type behind special Serde attributes like #[serde(with = "...")]. This mechanism ensures that rinf gen always produces exactly corresponding Dart code from Rust structs.
