Could anyone tell me the correct syntax for declaring anonymous suspend lambda with parameters? val ...

Could anyone tell me the correct syntax for declaring anonymous suspend lambda with parameters? val foo =suspend { a, b -> c } doesn’t seem to work

[Joffrey]

I think you have to specify the parameter types explicitly or the function type as a whole

[ephemient]

val foo: suspend (A, B) -> C = { a, b -> c }

Thanks!

Is this documented somewhere?

I think you can also use anonymous function syntax

[Zach Klippenstein (he/him) [MOD]]

val foo = suspend fun(a: A, b: B): C { return c }

[ephemient]

nope :(

[Zach Klippenstein (he/him) [MOD]]

You’re right, I thought that worked 😢

[ephemient]

I expect it should work after https://youtrack.jetbrains.com/issue/KT-22765/Introduce-suspend-modifier-for-lambdas is implemented, but that's been a long time…

Kotlin will also be able to calculate the meaning of life as soon as the ticket for adding that function to the stdlib is closed 😅
