struct ChoiceOf<Output>

You can use ChoiceOf to provide a group of regex components, each of which can be exclusively matched. In this example, regex successfully matches either a "CREDIT" or "DEBIT" substring:

let regex = Regex {
    ChoiceOf {
        "CREDIT"
        "DEBIT"
    }
}
let match = try regex.prefixMatch(in: "DEBIT    04032020    Payroll $69.73")
print(match?.0 as Any)
// Prints "DEBIT"
