Service Bus Output Bindings for Topics & Using Custom Properties

When sending messages via output binding for Service Bus Messages to Topics, the output parameter is of type "func.Out[str]" and only supports .set(val:str) and does not presently support setting ServiceBusMessage custom properties that would be useful when utilizing Topic Subscription filters, in particular.

Is there any plan to expand the output binding variables to support more than just string for Service Bus Messages? Sequence number, custom enqueuing time, other operations supported by the separate azure-service-bus Python library's ServiceBusMessage class?

首先跟踪由 func.Out[str] 表示的输出绑定，并将其当前功能与独立 azure-service-bus Python 库中的 ServiceBusMessage 类进行比较。明确应支持哪些消息属性和操作，然后将完成定义为一个达成共识的输出绑定接口，该接口能够设置 topic 订阅筛选器所需的自定义属性。
