如何将挂起函数作为显式参数传递给协程构建器? [英] how to pass suspend function as explicit parameter to coroutine builder?

问题描述

我正在研究 launch 协程构建器，它将协程代码作为 block: suspend CoroutineScope.() ->单位.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>

我错过了什么?

推荐答案

扩展函数引用的语法与成员函数相同:

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

launch(block = CoroutineScope::myFunction)
