bundle last STREAM frame and FIN bit #337
Description
Refer to 19.8. STREAM Frames
19.8. STREAM Frames
STREAM frames implicitly create a stream and carry stream data. The Type field in the STREAM frame takes the form 0b00001XXX (or the set of values from 0x08 to 0x0f). The three low-order bits of the frame type determine the fields that are present in the frame:
. The OFF bit (0x04) in the frame type is set to indicate that there is an Offset field present. When set to 1, the Offset field is present. When set to 0, the Offset field is absent and the Stream Data starts at an offset of 0 (that is, the frame contains the first bytes of the stream, or the end of a stream that includes no data).
. The LEN bit (0x02) in the frame type is set to indicate that there is a Length field present. If this bit is set to 0, the Length field is absent and the Stream Data field extends to the end of the packet. If this bit is set to 1, the Length field is present.
. The FIN bit (0x01) indicates that the frame marks the end of the stream. The final size of the stream is the sum of the offset and the length of this frame.
it's better to set the FIN bit on the last STREAM frame just like quic-go does, quic-go/quic-go#2504
