比较两个不同类型（但基础类型相同）的值

Question

如何比较两个类型不同但基础类型相同的变量的值。

type   SomeID    uint8
type   OtherID   uint8

func areEqual(sid SomeID, oid OtherID) bool {
   // error: mismatched types
   return sid == oid
}

Answer 1

如mkopriva所述，需要进行类型转换以比较这些值。

Answer 2

您可能不太准确，不需要记住基础类型

consensus_name

而且您可以更通用

    group    col1  col2             name   consensus_name
