```csharp
public interface IAsyncStream<T> : IAsyncBatchObservable<T>, IAsyncBatchProducer<T>, IAsyncObservable<T>, IAsyncObserver<T>, IAsyncStream, IComparable<IAsyncStream<T>>, IEquatable<IAsyncStream<T>>
```

This interface represents an object that serves as a distributed rendezvous between producers and consumers. It is similar to a Reactive Framework 

```csharp
Subject
```

 and implements 

```csharp
IObserver
```

 nor 

```csharp
IObservable
```

 interfaces.

## Type parameters

## Methods

- [GetAllSubscriptionHandles](/orleans/docs/api/csharp/microsoft.orleans.streaming/orleans.streams.iasyncstream-1/methods/getallsubscriptionhandles-4705f716/)
