A typeclass approach for default values in Scala. The topic of much scorn in Haskell, I find the existence of this typeclass to be superior to the general use Monoid everywhere as though it was a default value.
Default exists to allow you to have something that expresses what you want, even if it might not be what you actually need.
Default exists as a typeclass that allows
Default[A].default: A, it exposes in the package object
def default[A: Default]: A which you will likely find useful to remove the ceremony of summoning the typeclass to use.
To use this project in an existing SBT project with Scala 2.11 or a later version, add the following dependencies to your
build.sbt depending on your needs:
libraryDependencies ++= Seq( "io.chrisdavenport" %% "default" % "<version>" )
