Is there a Function1 equivalent for suspending function / coroutines? https://arrow-kt.io/docs/0.10/apidocs/arrow-core-data/arrow.core/-function1/index.html

No, and that's not possible afaik. What is your use-case? We're deprecating and removing Function1.

Related in case anyone is interested https://youtrack.jetbrains.com/issue/KT-18707

My goal is to write functional pipelines;

for instance i want to compose functions that are

F1 andThen F2 andThen F3 (and other functions that are offered by Function1)

[Pratik Tandel]

i’m hoping F1 can be a suspend func

[Pratik Tandel]

my use case is basically this:

i want to apply a sequence of linear transformations to some input type T, to convert it to output type F

Something like this but for suspend functions? https://github.com/arrow-kt/arrow-core/blob/master/arrow-syntax/src/main/kotlin/arrow/syntax/function/composition.kt

[Pratik Tandel]

yes that’d be great actually

[Pratik Tandel]

i don’t know if there are generic suspend functions; it’d also be nice to have those functions that can intermingle w/ suspending and non-suspending function

[simon.vergauwen]

A suspend lambda should work for non-suspending ones. In one of the latest 1.4.x version the added support for non-suspending lambda references to be used for suspend function arguments.

ok i might check it out
