Timeout handling
---
Timeout is a variation of cancellation. You can set timeout by `CancellationTokenSouce.CancelAfterSlim(TimeSpan)` and pass CancellationToken to async methods.
```csharp
var cts = new CancellationTokenSource();
cts.CancelAfterSlim(TimeSpan.FromSeconds(5)); // 5sec timeout.
try
{
await UnityWebRequest.Get("http://foo").SendWebRequest().WithCancellation(cts.Token);
}
catch (OperationCanceledException ex)
{
if (ex.CancellationToken == cts.Token)
{
UnityEngine.Debug.Log("Timeout");
}
}
```
> `CancellationTokenSouce.CancelAfter` is a standard api. However in Unity you should not use it because it depends threading timer. `CancelAfterSlim` is UniTask's extension methods, it uses PlayerLoop instead.
If you want to use timeout with other source of cancellation, use `CancellationTokenSource.CreateLinkedTokenSource`.
```csharp
var cancelToken = new CancellationTokenSource();
cancelButton.onClick.AddListener(()=>
{
cancelToken.Cancel(); // cancel from button click.
});
var timeoutToken = new CancellationTokenSource();
timeoutToken.CancelAfterSlim(TimeSpan.FromSeconds(5)); // 5sec timeout.
try
{
// combine token
var linkedTokenSource = CancellationTokenSource.CreateLinkedTokenSource(cancelToken.Token, timeoutToken.Token);
await UnityWebRequest.Get("http://foo").SendWebRequest().WithCancellation(linkedTokenSource.Token);
}
catch (OperationCanceledException ex)
{
if (timeoutToken.IsCancellationRequested)
{
UnityEngine.Debug.Log("Timeout.");
}
else if (cancelToken.IsCancellationRequested)
{
UnityEngine.Debug.Log("Cancel clicked.");
}
}
```
Optimize for reduce allocation of CancellationTokenSource for timeout per call async method, you can use UniTask's `TimeoutController`.
```csharp
TimeoutController timeoutController = new TimeoutController(); // setup to field for reuse.
async UniTask FooAsync()
{
try
{
// you can pass timeoutController.Timeout(TimeSpan) to cancellationToken.
await UnityWebRequest.Get("http://foo").SendWebRequest()
.WithCancellation(timeoutController.Timeout(TimeSpan.FromSeconds(5)));
timeoutController.Reset(); // call Reset(Stop timeout timer and ready for reuse) when succeed.
}
catch (OperationCanceledException ex)
{
if (timeoutController.IsTimeout())
{
UnityEngine.Debug.Log("timeout");
}
}
}
```
If you want to use timeout with other source of cancellation, use `new TimeoutController(CancellationToken)`.
```csharp
TimeoutController timeoutController;
CancellationTokenSource clickCancelSource;
void Start()
{
this.clickCancelSource = new CancellationTokenSource();
this.timeoutController = new TimeoutController(clickCancelSource);
}
```
Note: UniTask has `.Timeout`, `.TimeoutWithoutException` methods however, if possible, do not use these, please pass `CancellationToken`. Because `.Timeout` work from external of task, can not stop timeoutted task. `.Timeout` means ignore result when timeout. If you pass a `CancellationToken` to the method, it will act from inside of the task, so it is possible to stop a running task.
Progress

Some async operations for unity have `ToUniTask(IProgress<float> progress = null, ...)` extension methods.
@ -366,7 +458,7 @@ It indicates when to run, you can check [PlayerLoopList.md](https://gist.github.
`AsyncOperation` is returned from native timing. For example, await `SceneManager.LoadSceneAsync` is returned from `EarlyUpdate.UpdatePreloading` and after being called, the loaded scene's `Start` is called from `EarlyUpdate.ScriptRunDelayedStartupFrame`. Also `await UnityWebRequest` is returned from `EarlyUpdate.ExecuteMainThreadJobs`.
In UniTask, await directly and `WithCancellation` use native timing, `ToUniTask` uses specified timing. This is usually not a particular problem, but with `LoadSceneAsync`, it causes a different order of Start and continuation after await. So it is recommended not to use `LoadSceneAsync.ToUniTask`.

You can optimize loop cost slightly by remove unuse PlayerLoopTiming injection. You can call `PlayerLoopHelper.Initialize(InjectPlayerLoopTimings)` on initialize.
```csharp
var loop = PlayerLoop.GetCurrentPlayerLoop();
PlayerLoopHelper.Initialize(ref loop, InjectPlayerLoopTimings.Minimum); // minimum is Update | FixedUpdate | LastPostLateUpdate
```
`InjectPlayerLoopTimings` has three preset, `All` and `Standard`(All without last except LastPostLateUpdate), `Minimum`(`Update | FixedUpdate | LastPostLateUpdate`). Default is All and you can combine custom inject timings like `InjectPlayerLoopTimings.Update | InjectPlayerLoopTimings.FixedUpdate | InjectPlayerLoopTimings.PreLateUpdate`.
You can make error to use uninjected `PlayerLoopTiming` by [Microsoft.CodeAnalysis.BannedApiAnalyzers](https://github.com/dotnet/roslyn-analyzers/blob/master/src/Microsoft.CodeAnalysis.BannedApiAnalyzers/BannedApiAnalyzers.Help.md). For example, you can setup `BannedSymbols.txt` like this for `InjectPlayerLoopTimings.Minimum`.

async void vs async UniTaskVoid
---
`async void` is a standard C# task system so it does not run on UniTask systems. It is better not to use it. `async UniTaskVoid` is a lightweight version of `async UniTask` because it does not have awaitable completion and reports errors immediately to `UniTaskScheduler.UnobservedTaskException`. If you don't require awaiting (fire and forget), using `UniTaskVoid` is better. Unfortunately to dismiss warning, you're required to call `Forget()`.

UniTask can run on Unity Editor like an Editor Coroutine. However, there are some limitations.
* Delay, DelayFrame do not work correctly because they can not get deltaTime in editor. Return the result of the await immediately; you can use `DelayType.Realtime` to wait for the right time.
* UniTask.Delay's DelayType.DeltaTime, UnscaledDeltaTime do not work correctly because they can not get deltaTime in editor. Therefore run on EditMode, automatically change DelayType to `DelayType.Realtime` that wait for the right time.
* All PlayerLoopTiming run on the timing `EditorApplication.update`.
* `-batchmode` with `-quit` does not work because does not run `EditorApplication.update`(quit on single frame) so should not use `-quit` and quit manually with `Environment.Exit(0)`.
