Type Members

  1. final class materializeWith extends Annotation with StaticAnnotation

    Annotation which may be applied on methods of Implicits trait in MacroInstances to instruct MacroInstances.materialize macro how to implement these methods.

Value Members

  1. implicit macro def materialize[Implicits, Instances]: MacroInstances[Implicits, Instances]

    Materializes an instance of MacroInstances[Implicits, Instances].

    Materializes an instance of MacroInstances[Implicits, Instances]. This macro should not be invoked directly, it should only be used to materialize implicit parameters of RPC companion base classes, e.g. com.avsystem.commons.rest.DefaultRestApiCompanion.

    Example: 

    1. trait SomeRawRpc { ... }
class SomeMetadata[Real](...)

trait SomeInstances[Real} {
  def asReal: AsReal[SomeRawRpc, Real]
  def metadata: SomeMetadata[Real]
}

trait SomeImplicits { ... }
object SomeImplicits extends SomeImplicits

trait SomeRealRpc { ... }

      MacroInstances.materialize[SomeImplicits, SomeInstances[SomeRealRpc]] would generate:

      new MacroInstances[SomeImplicits, SomeInstances[SomeRealRpc]] {
  def apply(implicits: SomeImplicits): SomeInstances[SomeRealRpc] = {
    import implicits._
    new SomeInstances[SomeRealRpc] {
      def asReal: AsReal[SomeRawRpc, SomeRealRpc] = AsReal.materialize
      def metadata: SomeMetadata[Real] = RpcMetadata.materialize
    }
  }
}
