Constants

NGHTTP2_ALTSVC	The ALTSVC frame, which is defined in RFC 7383 <https://tools.ietf.org/html/rfc7838#section-4>_.
NGHTTP2_CANCEL	CANCEL
NGHTTP2_COMPRESSION_ERROR	COMPRESSION_ERROR
NGHTTP2_CONNECT_ERROR	CONNECT_ERROR
NGHTTP2_CONTINUATION	The CONTINUATION frame. This frame type won't be passed to any callbacks because the library processes this frame type and its preceding HEADERS/PUSH_PROMISE as a single frame.
NGHTTP2_DATA	The DATA frame.
NGHTTP2_DATA_FLAG_EOF	Indicates EOF was sensed.
NGHTTP2_DATA_FLAG_NONE	No flag set.
NGHTTP2_DATA_FLAG_NO_COPY	Indicates that application will send complete DATA frame in :type:nghttp2_send_data_callback.
NGHTTP2_DATA_FLAG_NO_END_STREAM	Indicates that END_STREAM flag must not be set even if NGHTTP2_DATA_FLAG_EOF is set. Usually this flag is used to send trailer fields with nghttp2_submit_request() or nghttp2_submit_response().
NGHTTP2_ENHANCE_YOUR_CALM	ENHANCE_YOUR_CALM
NGHTTP2_ERR_BAD_CLIENT_MAGIC	Invalid client magic (see :macro:NGHTTP2_CLIENT_MAGIC) was received and further processing is not possible.
NGHTTP2_ERR_BUFFER_ERROR	Out of buffer space.
NGHTTP2_ERR_CALLBACK_FAILURE	The user callback function failed. This is a fatal error.
NGHTTP2_ERR_CANCEL	Indicates that a processing was canceled.
NGHTTP2_ERR_DATA_EXIST	DATA or HEADERS frame for a given stream has been already submitted and has not been fully processed yet. Application should wait for the transmission of the previously submitted frame before submitting another.
NGHTTP2_ERR_DEFERRED	Used as a return value from :func:nghttp2_data_source_read_callback to indicate that data transfer is postponed. See :func:nghttp2_data_source_read_callback for details.
NGHTTP2_ERR_DEFERRED_DATA_EXIST	Another DATA frame has already been deferred.
NGHTTP2_ERR_EOF	The peer performed a shutdown on the connection.
NGHTTP2_ERR_FATAL	The errors < :enum:NGHTTP2_ERR_FATAL mean that the library is under unexpected condition and processing was terminated (e.g., out of memory). If application receives this error code, it must stop using that :type:nghttp2_session object and only allowed operation for that object is deallocate it using nghttp2_session_del().
NGHTTP2_ERR_FLOODED	Possible flooding by peer was detected in this HTTP/2 session. Flooding is measured by how many PING and SETTINGS frames with ACK flag set are queued for transmission. These frames are response for the peer initiated frames, and peer can cause memory exhaustion on server side to send these frames forever and does not read network.
NGHTTP2_ERR_FLOW_CONTROL	Flow control error
NGHTTP2_ERR_FRAME_SIZE_ERROR	The length of the frame is invalid, either too large or too small.
NGHTTP2_ERR_GOAWAY_ALREADY_SENT	GOAWAY has already been sent.
NGHTTP2_ERR_HEADER_COMP	Header block inflate/deflate error.
NGHTTP2_ERR_HTTP_HEADER	Invalid HTTP header field was received and stream is going to be closed.
NGHTTP2_ERR_HTTP_MESSAGING	Violation in HTTP messaging rule.
NGHTTP2_ERR_INSUFF_BUFSIZE	Insufficient buffer size given to function.
NGHTTP2_ERR_INTERNAL	Unexpected internal error, but recovered.
NGHTTP2_ERR_INVALID_ARGUMENT	Invalid argument passed.
NGHTTP2_ERR_INVALID_FRAME	The frame is invalid.
NGHTTP2_ERR_INVALID_HEADER_BLOCK	The received frame contains the invalid header block (e.g., There are duplicate header names; or the header names are not encoded in US-ASCII character set and not lower cased; or the header name is zero-length string; or the header value contains multiple in-sequence NUL bytes).
NGHTTP2_ERR_INVALID_STATE	Indicates that the context is not suitable to perform the requested operation.
NGHTTP2_ERR_INVALID_STREAM_ID	The stream ID is invalid.
NGHTTP2_ERR_INVALID_STREAM_STATE	The state of the stream is not valid (e.g., DATA cannot be sent to the stream if response HEADERS has not been sent).
NGHTTP2_ERR_NOMEM	Out of memory. This is a fatal error.
NGHTTP2_ERR_PAUSE	Callback was paused by the application
NGHTTP2_ERR_PROTO	General protocol error
NGHTTP2_ERR_PUSH_DISABLED	The server push is disabled.
NGHTTP2_ERR_REFUSED_STREAM	Stream was refused.
NGHTTP2_ERR_SESSION_CLOSING	The current session is closing due to a connection error or nghttp2_session_terminate_session() is called.
NGHTTP2_ERR_SETTINGS_EXPECTED	When a local endpoint expects to receive SETTINGS frame, it receives an other type of frame.
NGHTTP2_ERR_START_STREAM_NOT_ALLOWED	Starting new stream is not allowed (e.g., GOAWAY has been sent and/or received).
NGHTTP2_ERR_STREAM_CLOSED	The stream is already closed; or the stream ID is invalid.
NGHTTP2_ERR_STREAM_CLOSING	RST_STREAM has been added to the outbound queue. The stream is in closing state.
NGHTTP2_ERR_STREAM_ID_NOT_AVAILABLE	Stream ID has reached the maximum value. Therefore no stream ID is available.
NGHTTP2_ERR_STREAM_SHUT_WR	The transmission is not allowed for this stream (e.g., a frame with END_STREAM flag set has already sent).
NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE	The user callback function failed due to the temporal error.
NGHTTP2_ERR_TOO_MANY_INFLIGHT_SETTINGS	There are too many in-flight SETTING frame and no more transmission of SETTINGS is allowed.
NGHTTP2_ERR_UNSUPPORTED_VERSION	The specified protocol version is not supported.
NGHTTP2_ERR_WOULDBLOCK	Used as a return value from :type:nghttp2_send_callback, :type:nghttp2_recv_callback and :type:nghttp2_send_data_callback to indicate that the operation would block.
NGHTTP2_FLAG_ACK	The ACK flag.
NGHTTP2_FLAG_END_HEADERS	The END_HEADERS flag.
NGHTTP2_FLAG_END_STREAM	The END_STREAM flag.
NGHTTP2_FLAG_NONE	No flag set.
NGHTTP2_FLAG_PADDED	The PADDED flag.
NGHTTP2_FLAG_PRIORITY	The PRIORITY flag.
NGHTTP2_FLOW_CONTROL_ERROR	FLOW_CONTROL_ERROR
NGHTTP2_FRAME_SIZE_ERROR	FRAME_SIZE_ERROR
NGHTTP2_GOAWAY	The GOAWAY frame.
NGHTTP2_HCAT_HEADERS	The HEADERS frame which does not apply for the above categories, which is analogous to HEADERS in SPDY. If non-final response (e.g., status 1xx) is used, final response HEADERS frame will be categorized here.
NGHTTP2_HCAT_PUSH_RESPONSE	The HEADERS frame is the first headers sent against reserved stream.
NGHTTP2_HCAT_REQUEST	The HEADERS frame is opening new stream, which is analogous to SYN_STREAM in SPDY.
NGHTTP2_HCAT_RESPONSE	The HEADERS frame is the first response headers, which is analogous to SYN_REPLY in SPDY.
NGHTTP2_HD_INFLATE_EMIT	Indicates a header was emitted.
NGHTTP2_HD_INFLATE_FINAL	Indicates all headers were inflated.
NGHTTP2_HD_INFLATE_NONE	No flag set.
NGHTTP2_HEADERS	The HEADERS frame.
NGHTTP2_HTTP_1_1_REQUIRED	HTTP_1_1_REQUIRED
NGHTTP2_INADEQUATE_SECURITY	INADEQUATE_SECURITY
NGHTTP2_INTERNAL_ERROR	INTERNAL_ERROR
NGHTTP2_NO_ERROR	No errors.
NGHTTP2_NV_FLAG_NONE	No flag set.
NGHTTP2_NV_FLAG_NO_COPY_NAME	This flag is set solely by application. If this flag is set, the library does not make a copy of header field name. This could improve performance.
NGHTTP2_NV_FLAG_NO_COPY_VALUE	This flag is set solely by application. If this flag is set, the library does not make a copy of header field value. This could improve performance.
NGHTTP2_NV_FLAG_NO_INDEX	Indicates that this name/value pair must not be indexed ("Literal Header Field never Indexed" representation must be used in HPACK encoding). Other implementation calls this bit as "sensitive".
NGHTTP2_ORIGIN	The ORIGIN frame, which is defined by RFC 8336 <https://tools.ietf.org/html/rfc8336>_.
NGHTTP2_PING	The PING frame.
NGHTTP2_PRIORITY	The PRIORITY frame.

NGHTTP2_SETTINGS	The SETTINGS frame.
NGHTTP2_SETTINGS_ENABLE_PUSH	SETTINGS_ENABLE_PUSH
NGHTTP2_SETTINGS_HEADER_TABLE_SIZE	SETTINGS_HEADER_TABLE_SIZE
