  1. final case class Always[+A](f: () ⇒ A) extends Coeval[A] with Product with Serializable

    Permalink

    Constructs a lazy Coeval instance.

    Constructs a lazy Coeval instance.

    This type can be used for "lazy" values. In some sense it is equivalent to using a Function0 value.

  2. sealed abstract class Attempt[+A] extends Coeval[A] with Product

    Permalink

    The Attempt represents a strict, already evaluated result of a Coeval that either resulted in success, wrapped in a Now, or in an error, wrapped in a Error.

    The Attempt represents a strict, already evaluated result of a Coeval that either resulted in success, wrapped in a Now, or in an error, wrapped in a Error.

    It's the moral equivalent of scala.util.Try.

  3. final case class Error(ex: Throwable) extends Attempt[Nothing] with Product with Serializable

    Permalink

    Constructs an eager Coeval instance for a result that represents an error.

  4. final case class Now[+A](value: A) extends Attempt[A] with Product with Serializable

    Permalink

    Constructs an eager Coeval instance from a strict value that's already known.

  5. final class Once[+A] extends Coeval[A] with () ⇒ A

    Permalink

    Constructs a lazy Coeval instance that gets evaluated only once.

    Constructs a lazy Coeval instance that gets evaluated only once.

    In some sense it is equivalent to using a lazy val. When caching is not required or desired, prefer Always or Now.

  6. class TypeClassInstances extends DeferrableClass[Coeval] with MemoizableClass[Coeval] with RecoverableClass[Coeval, Throwable] with ComonadClass[Coeval] with MonadRecClass[Coeval]

    Permalink

    Groups the implementation for the type-classes defined in monix.types.

    Promote a non-strict value to an Coeval, catching exceptions in the process.

    Note that since Coeval is not memoized, this will recompute the value each time the Coeval is executed.

    Promote a non-strict value to a Coeval that is memoized on the first evaluation, the result being then available on subsequent evaluations.
