class OnOutputEndOfStream

After QueueInputEndOfStream() is sent by the StreamProcessor client,

within a reasonable duration the corresponding OnOutputEndOfStream()

will be sent by the StreamProcessor server. Similar to

QueueInputEndOfStream(), OnOutputEndOfStream() is sent a maximum of once

per stream.

No more stream data for this stream will be sent after this message. All

input data for this stream was processed.

While a StreamProcessor client is not required to

QueueInputEndOfStream() (unless the client wants to use

FlushEndOfStreamAndCloseStream()), if a StreamProcessor server receives

QueueInputEndOfStream(), and the client hasn't closed the stream, the

StreamProcessor server must generate a corresponding

OnOutputEndOfStream() if nothing went wrong, or must send

OnStreamFailed(), or must close the server end of the StreamProcessor

channel. An ideal StreamProcessor server would handle and report stream

errors via the error_ flags and complete stream processing without

sending OnStreamFailed(), but in any case, the above-listed options are

the only ways that an OnOutputEndOfStream() won't happen after

QueueInputEndOfStream().

There will be no more OnOutputPacket() or OnOutputConstraints() messages

for this stream_lifetime_ordinal after this message - if a server doesn't

follow this rule, a client should close the StreamProcessor channel.

The error_detected_before bool has the same semantics as the

error_detected_before bool in OnOutputPacket().
