Attempt

case class Attempt[+A](run: \/[Invalid, A]) extends Product with Serializable

Represents the result of an action, which may be the result itself or an Invalid (error).

An unsafe operation may be attempted using Attempt.safe(unsafeCall) for instance:

val r: Attempt[String] = for {
  a <- Attempt.safe { throw new RuntimeException("oh noes!") }
  b <- Attempt.ok("should be ok!")
} yield b

will result in an Attempt that holds an Invalid.Err with the RuntimeException in it.

This class does not – and will not – auto-magically catch exceptions for you in map/flatMap.
