Enums

Basic

Schema

enum Sample {
    Variant1 @1,
    Variant2 @2,
}

Languages

Rust

#[repr(u32)]
enum Sample {
    Variant1 = 1,
    Variant2 = 2,
    // N variants...
}

Go

type Sample uint32

const (
	SampleVariant1 Sample = 1
	SampleVariant2 Sample = 2
	// N variants...
)

Kotlin

enum class Sample(val value: Int) {
    Variant1(1),
    Variant2(2),
    // N variants...
}

TypeScript

enum Sample {
    Variant1 = 1,
    Variant2 = 2,
    // N variants...
}

Python

@dataclass
class Sample(Enum):
    VARIANT1 = 1
    VARIANT2 = 2

Advanced

Schema

enum Sample {
    Variant1(u32 @1, u16 @2) @1,
    Variant2 {
        field1: i64 @1,
        field2: bool @2,
    } @2,
}

Languages

Rust

enum Sample {
    Variant1(u32, u16),
    Variant2 { field1: i64, field2: bool },
    // N variants...
}

Go

type SampleVariant interface {
	sealed()
}

type Sample SampleVariant

type Sample_Variant1 struct {
	F1 uint32
	F2 uint16
}

func (v Sample_Variant1) sealed() {}

type Sample_Variant2 struct {
	Field1 int64
	Field2 bool
}

func (v Sample_Variant2) sealed() {}

// N variants...

Kotlin

sealed class Sample {
    class Variant1(
        val f1: UInt,
        val f2: UShort,
    ) : Sample()

    class Variant2(
        val field1: Long,
        val field2: Boolean,
    ) : Sample()

    // N variants...
}

TypeScript

enum SampleKind {
    Variant1,
    Variant2,
    // N variants...
}

interface SampleVariant1 {
    kind: SampleKind.Variant1;
    f1: number;
    f2: number;
}

interface SampleVariant2 {
    kind: SampleKind.Variant2;
    field1: number;
    field2: boolean;
}

Python

@dataclass
class SampleVariant1:
    tag: Literal["Variant1"]
    f1: int
    f2: int


@dataclass
class SampleVariant2:
    tag: Literal["Variant2"]
    field1: int
    field2: bool
