goutils (Golang UTILitieS) is a Golang implementation of some functions and data types to help other libraries.
You can see an extended doc in godocs.

Install it writing in terminal:

go get github.com/fmorenovr/goutils

Example:

If you wan to compare different interfaces with an Integer parse:

  var a, b interface{}
  a = 2
  b = 5
  goutils.IntComparator(a, b)
  // this should return 1 if a>b
  // this should return -1 if a<b
  // this should return 0 if a=b

Or define your own comparator function:

  // supose that this is your struct
  type MyDataType struct{
    ID int
    name string
  }

  // your comparator, you cna use this function as TypeComparator type function
  func MyComparator(a, b interface{}) int {
    AaAsserted := a.(MyDataType)
    bAsserted := b.(MyDataType)
    switch {
      case aAsserted.ID > bAsserted.ID:
        return 1
      case aAsserted.ID < bAsserted.ID:
        return -1
      default:
        return 0
    }
  }
