What's a good name for an alternative to the Result type to avoid name clashes with the stdlib?

[Petr Laštovička]

I used Resultus. It was kinda sus and didn't work out either 🐕

[Kristian Nedrevold]

What about Try?

[Chris Lee]

Personally find ‘Try’ confusing, it’s been tainted by try.

[Chris Lee]

I’m using ‘Result’ and dealing with the name clash, prioritizing the conceptual correctness of the name.

[Sam Painter]

Are you just typealiasing Try<T> or Either<Exception, T>? I’ve not found much application for a specific Result type and tend to just use Either.

[CLOVIS]

I have a single Failure type that I want to use everywhere, so I want to
typealias ???<T> = Either<Failure, T>

[CLOVIS]

Result is a great name, but since this alias will have the same generics signature as the one in the stdlib, it's too easy to mistake them

[Sam Painter]

Result really is a great name for that. I tend to use DomainError as my base failure type so DomainResult is probably what I would reach for if I wanted that type. Outcome is maybe the best direct synonym I can think of.

[CLOVIS]

Outcome is indeed pretty good 🤔

[CLOVIS]

Bonus point: out is not a keyword (unlike in), and it's a pretty good builder name:

fun ping() = out {

[Sam Painter]

I’m probably in the minority of Kotlin devs (I’m still mostly writing Java) but I tend to like a longer but more descriptive name anyway. Maybe outcomeOf

[Sam Painter]

I never thought about out not being a keyword though!

[CLOVIS]

To me, outcomeOf() takes a single value or a vararg (e.g. listOf(1), flowOf(1) ) and outcome {} takes a lambda that actually does the computation (e.g. either {}, flow {} )

[Petr Laštovička]

It's so called modifier keyword

[Sam Painter]

That’s a good point! I’m not the one to ask about Kotlin idiomatic naming ;)

[CLOVIS]

I really like that Kotlin tries its best not to make stuff like that keywords

I constantly stumble upon not being able to name a variable in , imagine if we couldn't name a variable open or data 😨
