An Exit[E, A] value describes how fibers end life. It has two possible values:

  • Exit.Success contain a success value of type A.
  • Exit.Failure contains a failure Cause of type E.

We can call run on our effect to determine the Success or Failure of our fiber:

import zio._import zio.Console._
for {  successExit <- ZIO.succeed(1).exit  _ <- successExit match {    case Exit.Success(value) =>      printLine(s"exited with success value: ${value}")    case Exit.Failure(cause) =>      printLine(s"exited with failure state: $cause")  }} yield ()
