Scala Throw Exception In Future at Archie Welch blog

Scala Throw Exception In Future. If this future is completed with an exception then the new future will also contain this exception. Here’s a little example of how exceptions work with scala futures, specifically looking at the oncomplete ‘failure’ case. It is possible that async functions may throw exceptions in case of errors. So, it’s safe to throw an exception in all functions that you pass to future (map, flatmap etc.). In this case, use recover to handle errors in functions that return. Val f = future { the future } val g = f map { x:. Future's.map will allow you to turn a success into a failure by simply throwing an exception in the mapping function, but it only uses. However, there’s a caveat… whenever it’s. When an exception is thrown from within a future, you can (should) use recover to handle it. Future = future { throw. Unlike java, all exceptions in scala are unchecked. We need to write a partial function in order to catch one explicitly.
