Streams

Streams support both subscription creation (the observable side) as well as event publication (the observer side). The interfaces are already shown above in the context of the discussion of stream factories, but one detail was omitted. In Rx, all concrete implementations of subjects implement IDisposable, but the ISubject<> interfaces dont. In IRP, the interface does implement IAsyncDisposable to enable the disposal of a stream in an IRP system:
interface IAsyncReactiveQubject<T> : IAsyncReactiveQubject<T, T>, IAsyncDisposable {}
IRPIAsyncDisposable
In fact, all interfaces representing hot artifacts in IRP implement IAsyncDisposable. As such, the interface describing subscriptions is defined as follows:
interface IAsyncReactiveQubscription : IAsyncDisposable {}

IAsyncDisposable使RxIRPIRPIRP
The use of IAsyncDisposable is the most straightforward way to map the Rx world to an isomorphic IRP world. However, it lacks the ability to provide additional parameters to the operation. Future iterations of IRP, discussed later on, may further decompose the formulation of the disposal intent from the submission of the operation to the target IRP system.
