Scala - Extracts a custom configuration object from a generic com.typesafe.config.Config

RichConfig.scala

package util.implicits

object RichConfig extends RichConfig
trait RichConfig {
  import com.typesafe.config.Config
  import net.ceedubs.ficus.Ficus._
  import util.types.Database

  implicit class RichConfig(config: Config) {

    def database: Database = {
      val name     = config.as[String]("db.name")
      val driver   = config.as[String]("db.driver")
      val url      = config.as[String]("db.url")
      val username = config.as[String]("db.username")
      val password = config.as[String]("db.password")
      Database(name, driver, url, username, password)
    }
  }
}

This example shows how a custom configuration object, in this case Database can be built and returned inline when a Database is needed but a com.typesafe.config.Config is passed.
