2.0.0-beta10 - 2023-07-15

New Feature

  • Add fromEffect(fa: => F[A]): F[A] to FxCtor and Fx (#524)

    Fx[IO].fromEffect(IO(1)) // IO[Int]
FxCtor[IO].fromEffect(IO(1)) // IO[Int]

  • Add make[A](fa: => F[A])(release: A => F[Unit]): ReleasableResource[F, A] to ResourceMaker[F[*]] (#527)

    def make[A](fa: => F[A])(release: A => F[Unit]): ReleasableResource[F, A]

    • Try

      val resourceMaker = ResourceMaker.usingResourceMaker
resourceMaker
  .make(Try(new SomeResource()))(a => Try(a.release())) // ReleasableResource[Try, SomeResource]
  .use { someResource =>
    // do something with someResource
    Try(result) // Try[ResultType]
  } // Try[ResultType]

    • Future

      val resourceMaker = ResourceMaker.futureResourceMaker
resourceMaker
  .make(Future(new SomeResource()))(a => Future(a.release())) // ReleasableResource[Future, SomeResource]
  .use { someResource =>
    // do something with someResource
    Future.successful(result) // Future[ResultType]
  } // Future[ResultType]

    • Cats Effect 2

      val resourceMaker = Ce2ResourceMaker.withResource
resourceMaker
  .make(IO(new SomeResource()))(a => IO(a.release())) // ReleasableResource[IO, SomeResource]
  .use { someResource =>
    // do something with someResource
    IO.pure(result) // IO[ResultType]
  } // IO[ResultType]

    • Cats Effect 3

      val resourceMaker = Ce3ResourceMaker.withResource
resourceMaker
  .make(IO(new SomeResource()))(a => IO(a.release())) // ReleasableResource[IO, SomeResource]
  .use { someResource =>
    // do something with someResource
    IO.pure(result) // IO[ResultType]
  } // IO[ResultType]

  • Add pure[A](a: A) and eval[A](fa: F[A]) to ResourceMaker (#534)

    trait ResourceMaker[F[*]] {
  ...

  def pure[A](a: A): ReleasableResource[F, A]

  def eval[A](fa: F[A]): ReleasableResource[F, A]
}

  • Add ReleasableResource.pure (#542)

    ReleasableResource.pure(resource: A): ReleasableResource[F, A]

    So A doesn't have to be AutoCloseable as it's just a pure value.

  • Add ReleasableResource.map and ReleasableResource.flatMap (#544)

    ReleasableResource.map(f: A => B)
ReleasableResource.flatMap(f: A => ReleasableResource[F, B])

  • Add Functor type-class for ReleasableResource (#548)

  • Add Applicative type-class for ReleasableResource (#550)

Changes

  • Remove unnecessary re-evaluation of ResourceMaker (#529)

    The following ResourceMaker constructor method is just val now.

    effectie.resource.ResourceMaker.usingResourceMaker

  • Rename withResource in Ce2ResourceMaker and Ce3ResourceMaker to maker (#530)

  • Move ResourceMaker and ReleasableResource to effectie-cats (#546)

    Having ReleasableResource in effectie-cats is required to have Functor and Monad type-classes.
