Kotlin-result Alternatives

Reviews and mentions

• Esito: Esito ambition is to be your return type for suspending functions

  How does this compare to other Result types in Kotlin? I.e. the one in the standard library, kotlin-result or any of the other ones? What functionality does this library have that is missing in the others? Can that be added to the existing libraries instead?

  Thats the convention followed by a lot of "Result" libraries. For example: https://github.com/michaelbull/kotlin-result, https://doc.rust-lang.org/rust-by-example/std/result.html.

  Arrow is not the only option.

  I've found this to be great. The library provides quite a few helper functions to suit different styles e.g. these are Rust-inspired

  i use this result to avoid the pain of multiple when's. I have a 'base view model' that extends the conventional one that has this function: protected fun vmLaunch(block: suspend () -> Unit){ viewModelScope.launch { onLoading?.invoke(true) block() onLoading?.invoke(false) } } To wrap the loading. Then the use of that ends up looking like: vmLaunch { streamingRepository.authForStreaming(deviceEntity) .onSuccess {} .onFailure {} }

• Using kotlin.Result causes runtime errors (up to 1.5.30-RC)

  Maybe consider kotlin-result in the mean time.

• Please explain the meaning and reasoning behind this: "Anyways, never catch exceptions when not strictly required! It's always easier to introduce an error handling later, than remove it!" in Kotlin.

  Here's an example library that provides it: https://github.com/michaelbull/kotlin-result

• so glad that result is finalized in 1.5

  Totally agree with you, but i found the perfect library for you and all of us https://github.com/michaelbull/kotlin-result nicely done! Give it a try

• How to Use Result Data Type

  You can check out kotlin-result. I have looked briefly at it and think it is interesting but did not yet time to experiment a lot with it

  It's a contrived example, but you get the idea. You can do the same thing with Arrow Core's Either type or with https://github.com/michaelbull/kotlin-result . If I had to do it again, I'd probably just use Arrow Core for my current project. Having Either, Validated, NonEmptyList, and all of the helpers is great. The only "problem" is that there's a very steep learning curve and it's very complex because of Kotlin's lack of higher-kinded types. So if you let yourself get "sucked in" to Arrow's way of doing things, you'll be trying to figure out the weird workarounds they're doing to encoded concepts like higher-kinded types and type classes into Kotlin, which really doesn't have those things.

• Has learning Rust influenced how you write other languages?

  But as far as enums + explicit error handling that's similar to Rust, that's actually not that hard. OCaml is a great example. OCaml also has async, but not multi-threading (yet!). Haskell and Scala are others. And you definitely can do enums and Result<> style returns in Swift and Kotlin- they're just not as nice as Rust, Scala, et al, because they have no syntax support for it (though you can implement something like Scala's for-comprehension in Kotlin: https://github.com/michaelbull/kotlin-result).

  Should I use someone else's: https://github.com/michaelbull/kotlin-result or https://arrow-kt.io/docs/apidocs/arrow-core-data/arrow.core/-either/ ?

  We built our own Result type for Kotlin as well. Arrow-KT has all the tools necessary - although you could just build this with a sealed class as well. After we built our own, I found kotlin-result: https://github.com/michaelbull/kotlin-result. I think at my next gig, I'll give that a shot.
