public CancellationToken CancellationToken { get; }
Cancellation token signals when call is cancelled. It is also triggered when the deadline is exceeeded or there was some other error (e.g. network problem).
Allows setting write options for the following write.
For streaming response calls, this property is also exposed as on IServerStreamWriter for convenience.
Both properties are backed by the same underlying value.
public Task WriteResponseHeadersAsync(Metadata responseHeaders)
Asynchronously sends response headers for the current call to the client. This method may only be invoked once for each call and needs to be invoked
before any response messages are written. Writing the first response message implicitly sends empty response headers ifWriteResponseHeadersAsynchaven't
been called yet.
