Return error result when transform digital type (except int) to bool #137
Description
As title said, when you transform int16, int64 or other digital type (not int) to bool, return an error result.
func try() {
var i int64 = 1
fmt.Println(cast.ToBool(i)) // false
}because cast only assert int type.
// ToBoolE casts an interface to a bool type.
func ToBoolE(i interface{}) (bool, error) {
i = indirect(i)
switch b := i.(type) {
case bool:
return b, nil
case nil:
return false, nil
case int:
if i.(int) != 0 {
return true, nil
}
return false, nil
case string:
return strconv.ParseBool(i.(string))
default:
return false, fmt.Errorf("unable to cast %#v of type %T to bool", i, i)
}
}
