如何在 go 中使用枚举？ [复制]

Question

在 golang 中是否有简单的枚举实现？ 类似以下内容？

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

Answer 1

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

或者，在Ultimate Visual Guide to Go Enums 应用示例

// 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]
}
