Enumerations

Enums define a type with a fixed set of named variants.

Basic Enum

kode

enum Color {
    Red,
    Green,
    Blue
}

enum Status {
    Active,
    Inactive,
    Pending
}

Enum with Associated Values

kode

enum Result {
    Success(value: int),
    Error(message: string),
    Pending
}

let outcome = Result.Success(42)
let error = Result.Error("Connection timeout")

Pattern Matching with Enums

kode

match (outcome) {
    Result.Success(value) => print("Got: ${value}"),
    Result.Error(msg) => print("Error: ${msg}"),
    Result.Pending => print("Still waiting...")
}

Enum with Methods

kode

enum Status {
    Active,
    Inactive,
    Pending
}

impl Status {
    fn isReady() -> bool {
        return this == Status.Active
    }
}

let status = Status.Active
if (status.isReady()) {
    print("Ready to go!")
}
