Kotlin Coroutine()是如何工作的S阻止了.

我读的是KEEP的Coroutine proposal.我在Coroutine Builders区偶然发现了这段代码.

fun launch(context: CoroutineContext = EmptyCoroutineContext, block: suspend () -> Unit) =
    block.startCoroutine(Continuation(context) { result ->
        result.onFailure { exception ->
            val currentThread = Thread.currentThread()
            currentThread.uncaughtExceptionHandler.uncaughtException(currentThread, exception)
        }
    })

并且startCoroutine是函数类型(suspend () -> T)的扩展函数

**
 * Starts a coroutine without a receiver and with result type [T].
 * This function creates and starts a new, fresh instance of suspendable computation every time it is invoked.
 * The [completion] continuation is invoked when the coroutine completes with a result or an exception.
 */
@SinceKotlin("1.3")
@Suppress("UNCHECKED_CAST")
public fun <T> (suspend () -> T).startCoroutine(
    completion: Continuation<T>
) {
    createCoroutineUnintercepted(completion).intercepted().resume(Unit)
}

我想知道startCoroutine()函数如何执行它正在扩展的函数block.因为我在代码中看不到任何this().

createCoroutineUnintercepted()还扩展了相同的函数类型，但那里没有源代码实现.

@SinceKotlin("1.3")
public expect fun <T> (suspend () -> T).createCoroutineUnintercepted(
    completion: Continuation<T>
): Continuation<Unit>

询问ChatGPT没有带来任何答案.它说

当您调用block.startCoroutine(...)时，您实际上是在启动块的执行.

try 实现一个简单的函数类型扩展example，但似乎不起作用.

有谁能告诉我这个扩展函数类型是如何工作的吗？

编译器在挂起这方面的函数时也会施展什么魔力吗？
