Release Date: 2018-02-27 // about 6 years ago

  • 🚧 Maintenance version

    👌 Improvements

    ⬆️ This library upgrades cats-effect to 0.9.0 but also provides

    less restrictive implicit instances for Async[Eff[R, ?]] when R contains cats.effect.IO or io.monix.Task effects

    2 instances for Effect[Eff[R, ?]] when R contains cats.effect.IO or io.monix.Task effects.
    Those instances can only be used if there is a way to transform Eff[R, ?] into cats.effect.IO (respectively io.monix.Task)

    Previously the Async instances were only define through the Effect instances in point 2, because Effect extends Async.
    Now the Async instances are implicits and the Effect instances are explicit (no implicit keyword).
