如何在go中使用枚举？[重复]

Question

Go语言中是否有枚举的简单实现？像下面这样的东西？

type status enum[string] {
    pending = "PENDING"
    active = "ACTIVE"
}

Answer 1

像下面这样的东西？

现在还没有

请阅读以下内容：Go中表示枚举的惯用方法是什么？

Answer 2

const (
    statusPending = "PENDING"
    statusActive  = "ACTIVE"
)

或者，在“终极视觉指南”中应用该示例进行枚举

// Declare a new type named status which will unify our enum values
// It has an underlying type of unsigned integer (uint).
type status int

// Declare typed constants each with type of status
const (
    pending status = iota
    active
)

// String returns the string value of the status
func (s status) String() string {
    strings := [...]string{"PENDING", "ACTIVE"}

    // prevent panicking in case of status is out-of-range
    if s < pending || s > active {
        return "Unknown"
    }

    return strings[s]
}
