When using things like Futures, it is often required to have an implicit ExecutionContext When working with Futures, you will often find that importing the whole concurrent GuideĪ more detailed guide to Futures and Promises, including discussion and examples This package object contains primitives for concurrent and parallel programming. For example, on the JVM, String is an alias for. Other aliases refer to classes provided by the underlying platform. Some of these identifiers are type aliases provided as shortcuts to commonly used classes. Identifiers in the scala package and the scala.Predef object are always in scope by default.
