NonFatal

object NonFatal

A classifier of non-fatal Exceptions.

Developers should prefer using scala.util.control.NonFatal from the Scala standard library.

Annotations
@deprecated
Deprecated

(Since version 2016-11-21) Use scala.util.control.NonFatal instead

Note

Scala added NonFatal to the standard library in Scala 2.10, while Twitter's util needed to provide this for users who were still on Scala 2.9 at the time.
