Struct UnionCodegen 

pub struct UnionCodegen {
    pub type_name: Option<String>,
    pub derive: Option<Vec<String>>,
    pub variant_types: Option<bool>,
    pub variant_types_suffix: Option<String>,
}

Codegen settings for union types.

Corresponds to $types.union-codegen in the schema. Used via $ext-type.codegen on union type definitions. Includes flattened fields from $types.base-codegen.

Example

@ $types.my-union {
  $variant: union
  $codegen {
    type = "MyUnion"
    variant-types = true
    variant-types-suffix = "Variant"
  }
  variants.a = `text`
  variants.b = `integer`
}

Fields

type_name: Option<String>

Override the generated type name (from base-codegen).

derive: Option<Vec<String>>

Override the list of derive macros (from base-codegen).

variant_types: Option<bool>

Generate separate types for each variant instead of struct-like variants.

variant_types_suffix: Option<String>

Suffix for variant type names (e.g., “Type” -> TextType, IntegerType).
