Wrap method vs chain method

Imagine we have the following:



sealed trait Foo
case class FullFoo[A](foo: A) extends Foo
case object EmptyFoo extends Foo


and



def liftToFoo[A](opt: Option[A]): Foo = 
opt.map(a => FullFoo(a)).getOrElse(EmptyFoo)


We can easily do:



liftToFoo(Some(123)) // FullFoo(123)
liftToFoo(None) // EmptyFoo


But I'm curious if there's some "chainable" way to call this (rather than wrapping the method like above):



Some(123).someFunction(liftToFoo)  // FullFoo(123)

  • I'm trying to avoid using an implicit class to achieve this style. Curious if there's something I can use already.

Not exactly what you're looking for but perhaps a little closer than what you've got.



Some(123).fold(EmptyFoo:Foo)(FullFoo(_))

  • A) Yeah, but you said you were "trying to avoid an implicit class". B) Success()? Failure()? That's a Try, not a Foo.

  • Re: implicits, yeah totally! Lol I hacked together this "Foo" example, but was really thinking of applying it with a Try :P You caught me in some Frankenstein copy/paste :)
