EnumConvertible

Protocols for enum abstraction. This library contains 2-5 case enum abstract protocols.

Example

extension MyEnumIntOrString: Enum2Convertible {
  var asEnum: AnyEnum2<Int, String> {
    ...
  }
}

func argumentIsAnyEnumIntOrString<E: Enum2Convertible>(arg: E) 
  where E.case0 == Int
  , E.case1 == String 
{
  switch arg.asEnum {
    case .case0(let intValue):
    ...
  }
}

argumentIsAnyEnumIntOrString(arg: myEnumValue)

Needs 6 or more cases...

Adding environment variable ENUM_CONVERTIBLE_MAX_SERIAL_NUMBER then EnumConvertible.swift will contains 2-ENUM_CONVERTIBLE_MAX_SERIAL_NUMBER case enum protocols. Or, adding ENUM_CONVERTIBLE_SPECIFIC_NUMBERS, it should be comma separated numerics, then EnumConvertible.swift contains the specific case enum protocols. This project generate code using gyb, and EnumConvertible.xcodeproj contains code generating script. If you use Carthage, it work well injecting custom environment variable.
