AsyncThrowingStream.Continuation
A mechanism to interface between synchronous code and an asynchronous stream.
Declaration
struct ContinuationOverview
The closure you provide to the AsyncThrowingStream in init(_:bufferingPolicy:_:) receives an instance of this type when invoked. Use this continuation to provide elements to the stream by calling one of the yield methods, then terminate the stream normally by calling the finish() method. You can also use the continuation’s finish(throwing:) method to terminate the stream by throwing an error.
