trait Compose[F[_, _]] extends Serializable

Must obey the laws defined in cats.laws.ComposeLaws.

Here's how you can use >>> and <<< Example:

scala> import cats.implicits._
scala> val f : Int => Int = (_ + 1)
scala> val g : Int => Int = (_ * 100)
scala> (f >>> g)(3)
res0: Int = 400
scala> (f <<< g)(3)
res1: Int = 301
