  7. def doNotAwait(eitherT: EitherT[Future, _, _], failureMessage: => String, level: Level = Level.ERROR)(implicit executionContext: ExecutionContext, loggingContext: ErrorLoggingContext): Unit

    Discard eitherT and log an error if it does not result in a Right.

    Discard eitherT and log an error if it does not result in a Right. This is useful to document that an EitherT[Future,_,_] is intentionally not being awaited upon.

  11. def fromFuture[E, A](fut: Future[A], errorHandler: (Throwable) => E)(implicit ec: ExecutionContext): EitherT[Future, E, A]

    Construct an EitherT from a possibly failed future.

  14. def ifThenET[F[_], L](cond: Boolean)(then: => EitherT[F, L, _])(implicit F: Applicative[F]): EitherT[F, L, Unit]

  16. def leftSubflatMap[F[_], A, B, C, BB >: B](x: EitherT[F, A, B])(f: (A) => Either[C, BB])(implicit F: Functor[F]): EitherT[F, C, BB]
  17. def liftFailedFuture[E, A](fut: Future[Either[E, A]], errorHandler: (Throwable) => E)(implicit executionContext: ExecutionContext): EitherT[Future, E, A]

    Lift a failed future into a Left value.

  18. def logOnError[E, R](result: EitherT[Future, E, R], message: String, level: Level = Level.ERROR)(implicit executionContext: ExecutionContext, loggingContext: ErrorLoggingContext): EitherT[Future, E, R]

    Log message if result fails with an exception or results in a Left

  19. def logOnErrorU[E, R](result: EitherT[FutureUnlessShutdown, E, R], message: String, level: Level = Level.ERROR)(implicit executionContext: ExecutionContext, loggingContext: ErrorLoggingContext): EitherT[FutureUnlessShutdown, E, R]

  23. def onErrorOrFailure[A, B](errorHandler: () => Unit)(fn: => EitherT[Future, A, B])(implicit executionContext: ExecutionContext): EitherT[Future, A, B]

    Similar to finallyET but will only call the provided handler if fn returns a left/error or fails.

  26. def timed[E, R](timerMetric: Timer)(code: => EitherT[Future, E, R])(implicit executionContext: ExecutionContext): EitherT[Future, E, R]

    Measure time of EitherT-based calls, inspired by upstream com.daml.metrics.Timed.future

  27. def toFuture[L <: Throwable, R](x: EitherT[Future, L, R])(implicit executionContext: ExecutionContext): Future[R]

    Transform an EitherT into a Future.failed on left

    Transform an EitherT into a Future.failed on left

    Comes handy when having to return io.grpc.StatusRuntimeExceptions
