// 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 }
