Type Members

  1. type ::[E] = HCons[E, Self]

    The type of prepending an element of type E to this HList

  2. abstract type Head

    The type of the first element

  3. abstract type Self <: HList

    The type of this HList object

  4. abstract type Tail <: HList

    The type of the tail of this HList

Abstract Value Members

  1. abstract def head: Head

    (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.
