- * The implementation of this function must read at most |length|
- * bytes of data from |source| (or possibly other places) and store
- * them in |buf| and return number of data stored in |buf|. If EOF is
- * reached, set :enum:`NGHTTP2_DATA_FLAG_EOF` flag in |*data_flags|.
- *
- * Sometime it is desirable to avoid copying data into |buf| and let
- * application to send data directly. To achieve this, set
- * :enum:`NGHTTP2_DATA_FLAG_NO_COPY` to |*data_flags| (and possibly
- * other flags, just like when we do copy), and return the number of
- * bytes to send without copying data into |buf|. The library, seeing
- * :enum:`NGHTTP2_DATA_FLAG_NO_COPY`, will invoke
- * :type:`nghttp2_send_data_callback`. The application must send
- * complete DATA frame in that callback.
- *
- * If this callback is set by `nghttp2_submit_request()`,
- * `nghttp2_submit_response()` or `nghttp2_submit_headers()` and
- * `nghttp2_submit_data()` with flag parameter
- * :enum:`NGHTTP2_FLAG_END_STREAM` set, and
- * :enum:`NGHTTP2_DATA_FLAG_EOF` flag is set to |*data_flags|, DATA
- * frame will have END_STREAM flag set. Usually, this is expected
- * behaviour and all are fine. One exception is send trailer fields.
- * You cannot send trailer fields after sending frame with END_STREAM
- * set. To avoid this problem, one can set
- * :enum:`NGHTTP2_DATA_FLAG_NO_END_STREAM` along with
- * :enum:`NGHTTP2_DATA_FLAG_EOF` to signal the library not to set
- * END_STREAM in DATA frame. Then application can use
- * `nghttp2_submit_trailer()` to send trailer fields.
- * `nghttp2_submit_trailer()` can be called inside this callback.
- *
- * If the application wants to postpone DATA frames (e.g.,
- * asynchronous I/O, or reading data blocks for long time), it is
- * achieved by returning :enum:`NGHTTP2_ERR_DEFERRED` without reading
- * any data in this invocation. The library removes DATA frame from
- * the outgoing queue temporarily. To move back deferred DATA frame
- * to outgoing queue, call `nghttp2_session_resume_data()`. In case
- * of error, there are 2 choices. Returning
- * :enum:`NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE` will close the stream
- * by issuing RST_STREAM with :enum:`NGHTTP2_INTERNAL_ERROR`. If a
- * different error code is desirable, use
- * `nghttp2_submit_rst_stream()` with a desired error code and then
- * return :enum:`NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE`. Returning
- * :enum:`NGHTTP2_ERR_CALLBACK_FAILURE` will signal the entire session

- * @function

- * Inflates name/value block stored in |in| with length |inlen|. This
- * function performs decompression. For each successful emission of
- * header name/value pair, :enum:`NGHTTP2_HD_INFLATE_EMIT` is set in
- * |*inflate_flags| and name/value pair is assigned to the |nv_out|
- * and the function returns. The caller must not free the members of

- *
- * The |nv_out| may include pointers to the memory region in the |in|.
- * The caller must retain the |in| while the |nv_out| is used.
- *
- * The application should call this function repeatedly until the
- * ``(*inflate_flags) & NGHTTP2_HD_INFLATE_FINAL`` is nonzero and
- * return value is non-negative. This means the all input values are
- * processed successfully. Then the application must call
- * `nghttp2_hd_inflate_end_headers()` to prepare for the next header
- * block input.
- *
- * The caller can feed complete compressed header block. It also can
- * feed it in several chunks. The caller must set |in_final| to
- * nonzero if the given input is the last block of the compressed
- * header.
- *
- * This function returns the number of bytes processed if it succeeds,
- * or one of the following negative error codes:

- * :enum:`NGHTTP2_ERR_NOMEM`
- * Out of memory.
- * :enum:`NGHTTP2_ERR_HEADER_COMP`
- * Inflation process has failed.
- * :enum:`NGHTTP2_ERR_BUFFER_ERROR`

- * we observed so far.
- *
- * You might imagine this is really easy. But no. HTTP/2 is
- * asynchronous protocol, and usually client and server do not
- * share the complete picture of open/closed stream status. For
- * example, after server sends RST_STREAM for a stream, client may
- * send trailer HEADERS for that stream. If naive server detects
- * that, and issued connection error, then it is a bug of server
- * implementation since client is not wrong if it did not get
- * RST_STREAM when it issued trailer HEADERS.
- *
- * For server session, we remember closed streams as long as the
- * sum of closed streams and opened streams are under current max
- * concurrent streams. We can use these closed streams to detect
- * the error in some cases.
- *
- * If the stream cannot be found in either closed or opened
- * streams, it is considered to be closed, or it has not exist
- * (e.g., peer skipped sending the stream). Actually, it is
- * impossible to detect which is which, since that information was
- * lost forever. For these cases, we send back GOAWAY with
- * PROTOCOL_ERROR.
- *
- * If the stream is found, and we know that it is in half closed
- * (remote), or closed by peer's explicit action (e.g., received
- * RST_STREAM from peer, or peer sends HEADERS/DATA frame with
- * END_STREAM), getting new frame on that stream is clearly error.
- * In this case, we send GOAWAY with error code STREAM_CLOSED.
- *
- * There is one corner case here. Server can change the max
- * concurrent streams. The initial value of max concurrent
- * streams is unlimited (NGHTTP2_DEFAULT_MAX_CONCURRENT_STREAMS,
- * which is UINT32_MAX). When sending out SETTINGS with
- * MAX_CONCURRENT_STREAMS, we save its value as pending max
- * concurrent streams, and use it as a cap to remember closed
- * stream to save memory. This means that we might not sure that
- * stream surely closed or has not exist when it is not found in
- * closed or opened stream. To workaround this issue, we ignore
- * incoming frame if the current max concurrent streams is
- * NGHTTP2_DEFAULT_MAX_CONCURRENT_STREAMS, and pending max
- * concurrent streams is less than that.
