trait QuasiIO[F[_]] extends QuasiPrimitives[F]

Evidence that F is _almost_ like an IO monad, but not quite – because we also allow an impure izumi.fundamentals.platform.functional.Identity instance, for which maybeSuspend does not actually suspend!

If you use this interface and forget to add manual suspensions with by-name parameters everywhere, you're going to get weird behavior for Identity instance.

This interface serves internal needs of distage for interoperability with all existing Scala effect types and also with Identity, you should NOT refer to it in your code if possible.

This type is public because you may want to define your own instances, if a suitable instance of izumi.distage.modules.DefaultModule is missing for your custom effect type. For application logic, prefer writing against typeclasses in izumi.functional.bio or cats instead.

See also

izumi.distage.modules.DefaultModule - DefaultModule makes instances of QuasiIO for cats-effect, ZIO, monix, monix-bio, Identity and others available for summoning in your wiring automatically TODO: we want to get rid of this by providing Identity implementations for relevant BIO typeclasses See https://github.com/7mind/izumi/issues/787

  3. abstract def definitelyRecoverUnsafeIgnoreTrace[A](action: => F[A])(recover: (Throwable) => F[A]): F[A]

    A stronger version of handleErrorWith (cats-effect) or catchAll (ZIO), the difference is that this will _also_ intercept Throwable defects in ZIO, not only typed errors.

    Note

    This function is meant for _RECOVERING_ errors, for _REPORTING_ errors use definitelyRecoverWithTrace and include the full trace of the error in the report.

  4. abstract def definitelyRecoverWithTrace[A](action: => F[A])(recoverWithTrace: (Throwable, Trace[Throwable]) => F[A]): F[A]

    Like definitelyRecoverUnsafeIgnoreTrace, but the second parameter to the callback contains the effect's debugging information, possibly convertable to a Throwable via Exit.Trace#toThrowable, or that could be used to mutably enhance the left-hand-side Throwable value via Exit.Trace#unsafeAttachTrace

    Note

    Exit.Trace#unsafeAttachTrace may perform side-effects to the original Throwable argument on the left, the left throwable should be DISCARDED after calling the callback. (e.g. in case of ZIO, the callback will mutate the throwable and attach a ZIO Trace to it.)
