Hi, I'm wondering if there is a way to implement something like suspend fun Transacter.transactionWithContext, but that would return result. I tried something like this, but I feel stuck
In Couroutine Extensions:

suspend fun <T: Any> Transacter.transactionWithContextResult(
    coroutineContext: CoroutineContext,
    noEnclosing: Boolean = false,
    body: TransactionWithReturn<T>.() -> T
): T {
    return withContext(coroutineContext) {
        [e-mail](noEnclosing) { body }
    }
}

Using in DatabaseHelper:

suspend fun getAllItems(): List<Item> {
    dbRef.transactionWithContextResult<List<Item>>(backgroundDispatcher) {
        dbQueries.getAllItems(::mapItemsSelecting).executeAsList()
    }
}

I guess it’s a better question for #squarelibraries but what exactly does not work here? The type cannot be inferred I assume?

you have to invoke your body actually, so change it to either body.invoke() or just body()

🤦‍♀️ Thanks! I'll give it a try later :)
