In Scala, is there a pre-existing library function for converting exceptions to Options?

Question

This is basically to wrap java factory methods which throw exceptions if the item can\'t be created based on the inputs. I\'m looking for something in the base library like:

As of scala 2.10, you can run your code (e.g. factory method) in a scala.util.Try and then convert it with toOption:

import scala.util.Try
Try("foo".toInt).toOption  // None
Try("7".toInt).toOption    // Some(7)

Or translated to your original example:

val id: Option[UUID] = Try(UUID.fromString("this will produce None")).toOption
