# multiplatform

not sure if this is the right place, i’m a little baffled trying to make this work and i can’t seem to find anything on google to answer my questions.

function:

inline fun <reified T> withResult(
    method: Result<T>,
    onFailure: (errors: List<Throwable>) -> Unit
): T {
        @Suppress("IMPLICIT_CAST_TO_ANY")
        val methodResult = when (method) {
            is Result.Success -> { method.t }
            is Result.Failure -> { onFailure.invoke(method.errors) }
        }
        return methodResult as T
}

usage:

val r = withResult(method) { return Result.Failure(it) }

i can get this function to work on jvm, however it does not work on js. it results in a ClassCastException
the transpiled js appears to show that instead of invoking onFailure it is only assigned to methodResult.

also, this is a custom sealed class Result not kotlin.Result

i’m hoping i’m missing something obvious here. 😅

tl;dr drop invoke() and it works
