abstract class FromString[+T] extends PartialFunction[String, T]

A general mechanism for defining how a command line argument (always a String) is transformed into an arbitrary type. A few example instances are in the companion object, but in general either IntFromString will suffice or you'll want custom transformers.

    (Since version 2.12.16) Use formatString.format(value) instead of value.formatted(formatString), or use the f"" string interpolator. In Java 15 and later, formatted resolves to the new method in String which has reversed parameters.

    (Since version 2.13.0) Use -> instead. If you still wish to display it as one character, consider using a font with programming ligatures such as Fira Code.
