12/22/2016, 2:27 PMthat's workaround for your case - h
hackerham
12/22/2016, 2:28 PMOh, can you check if it compiles? - h
hackerham
12/22/2016, 2:28 PMand add it to the issue if its not 🙂 - v
vgrechka
12/22/2016, 2:28 PMyes, that compiles - e

12/22/2016, 2:33 PM@hackerham: I'm lost in asyncresult discussion. What problem you want to solve? Can you give some links to an API you need to convert to coroutines? - d
Deactivated User
12/22/2016, 2:43 PMhow it is supposed to disable the warning about corrutines? I'm using a gradle project and I have tried to put kotlin.coroutines=enable in local properties and gradle.properties + Settings -> Kotlin Compiler -> Coroutines -> Enabled, but still have the warning - h

hackerham
12/22/2016, 2:45 PMthey accept lambdas with either one complex AsyncResult, or two params: (err, res) - h
hackerham
12/22/2016, 2:45 PMthat's the other form of continuation interface: just instead of two methods there is one but with two params or a sealed class instance - h
hackerham
12/22/2016, 2:48 PMI and @Deactivated User agreed that solution is a extension function for Continuation that can be passed as a lambda - h
hackerham
12/22/2016, 2:49 PMbut may be you can come up with something that wouldnt require extra object alloc for every method call - e
elizarov
12/22/2016, 2:51 PMWhy do you care about alloc? It an sync call. Its cost is already much higher than even a few extra objects.🍪 1 - e
elizarov
12/22/2016, 2:53 PMvx { doSomeVertexOperation(args, it) }🍪 1 - e
elizarov
12/22/2016, 2:53 PMWrite yourself a helper vx function and live happily - d
Deactivated User
12/22/2016, 2:53 PMthat looks pretty elegant to me - h
hackerham
12/22/2016, 2:53 PMoh, that's brilliant! - h
hackerham
12/22/2016, 2:55 PM@Deactivated User i think we have a winner 🙂 - d
Deactivated User
12/22/2016, 2:55 PMgoing to try right now - d
Deactivated User
12/22/2016, 2:55 PMto see if it works with type inference - e
elizarov
12/22/2016, 2:55 PMIt can beinline suspend fun vx(...) - h
hackerham
12/22/2016, 2:56 PM@Deactivated User it'll work if you specify type in the "vx<T>" and not as a function return type - d
Deactivated User
12/22/2016, 2:56 PMinline suspend fun <T> vx(callback: (AsyncResult<T>) -> Unit) { }👍 1 - d
Deactivated User
12/22/2016, 2:57 PMI'0m trying this signature - d
Deactivated User
12/22/2016, 2:57 PMbut not sure, I'm still trying - e
elizarov
12/22/2016, 2:57 PMInference might be an issuer. File A change request to YT if it does not work. - h
hackerham
12/22/2016, 2:58 PMno, its not that, it must have no params but return type as continuation - e
elizarov
12/22/2016, 2:58 PMReturn type must be T - e
elizarov
12/22/2016, 2:58 PMCallback has right type. - h
hackerham
12/22/2016, 2:59 PMCopy codeinline suspend fun <T> vx(block: Handler<T>.() -> Unit) = suspendCoroutine<T> { ... }
