如何将暂停功能作为显式参数传递给协程生成器?

问题描述

我正在寻找将协程代码作为block: suspend CoroutineScope.() -> Unit的launch协程生成器.我们通常将代码作为lambda传递.但是，我想知道如何将此函数作为显式参数传递给启动函数.

I'm looking into launch coroutine builder which takes coroutine code as block: suspend CoroutineScope.() -> Unit. We usually pass the code as lambda. However, I was wondering how to pass this function as explicit parameter to launch function.

coroutineScope {
    launch(block = ::myFunction)
}

suspend fun CoroutineScope.myFunction(): Unit {
    // coroutine code
}

出现以下错误

Type mismatch.
Required:
suspend CoroutineScope.() → Unit
Found:
KSuspendFunction0<Unit>

我想念的是什么?

推荐答案

扩展函数引用的语法与成员函数的语法相同:

The syntax for extension function references is the same as for member functions:

launch(block = CoroutineScope::myFunction)
