Now

cats.Now

final case class Now[A](value: A) extends Leaf[A]

Construct an eager Eval[A] instance.

In some sense it is equivalent to using a val.

This type should be used when an A value is already in hand, or when the computation to produce an A value is pure and very fast.

Concrete methods

Ensure that the result of the computation (if any) will be memoized.

Practically, this means that when called on an Always[A] a Later[A] with an equivalent computation will be returned.

Attributes

Inherited methods

Lazily perform a computation based on an Eval[A], using the function f to produce an Eval[B] given an A.

This call is stack-safe -- many .flatMap calls may be chained without consumed additional stack during evaluation. It is also written to avoid left-association problems, so that repeated calls to .flatMap will be efficiently applied.

Computation performed in f is always lazy, even when called on an eager (Now) instance.

Attributes

Source: Eval.scala

Transform an Eval[A] into an Eval[B] given the transformation function f.

This call is stack-safe -- many .map calls may be chained without consumed additional stack during evaluation.

Computation performed in f is always lazy, even when called on an eager (Now) instance.
