Go1.18都出泛型了速来围观

// comparable is an interface that is implemented by all comparable types
// (booleans, numbers, strings, pointers, channels, arrays of comparable types,
// structs whose fields are all comparable types).
// The comparable interface may only be used as a type parameter constraint,
// not as the type of a variable.
//翻译如下
//comparable是由所有可比较类型实现的接口
//（布尔、数字、字符串、指针、通道、类似类型的数组、，
//字段均为可比较类型的结构）。
//可比接口只能用作类型参数约束，
//不是作为变量的类型。
type comparable interface{ comparable }
