Struct FieldEnum 

pub struct FieldEnum {
    pub discriminant: FieldPrimitive,
    pub variants: Vec<EnumVariant>,
    pub field_mask: PathFieldSet,
    pub sub_projection: Projection,
}

Maps an embedded enum field to its discriminant column and per-variant data columns.

The discriminant column always stores the active variant’s integer discriminant. Each data variant additionally has nullable columns for its fields; unit variants have no extra columns (all variant-field columns are NULL for them).

Fields

discriminant: FieldPrimitive

Mapping for the discriminant column.

variants: Vec<EnumVariant>

Per-variant mappings, in the same order as app::EmbeddedEnum::variants.

field_mask: PathFieldSet

Update coverage mask for the enum field (singleton: the whole enum changes atomically).

sub_projection: Projection

Sub-projection from the root model field to this enum field.
