【深入理解Kotlin协程】如何将回调改写成挂起函数

最简单的复写挂起函数的回调：

suspend fun suspendFunc() = suspendCoroutine<Int> {
   
    it.resumeWith(Result.success(1))
}

只不过真正的挂起需要真正的切换线程，如果直接调用的话相当于没有挂起。

suspend fun getUserSuspend(name: String) = suspendCoroutine<User> {
    continuation ->
    githubApi.getUserCallback(name).enqueue(object: Callback<User>{
   
        override fun onFailure(call: Call<User>, t: Throwable) =
            continuation.resumeWithException(t)
        override fun onResponse(call: Call<User>, response: Response<User>) =
            response.takeIf {
    it.isSuccessful }?.body()?.let(continuation::resume)
                ?: continuation.resumeWithException(HttpException(response))
    })
}
suspend fun main(){
