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_PROTOCOL_ERROR PROTOCOL_ERROR NGHTTP2_PUSH_PROMISE The PUSH_PROMISE frame. NGHTTP2_REFUSED_STREAM REFUSED_STREAM NGHTTP2_RST_STREAM The RST_STREAM frame. NGHTTP2_SETTINGS The SETTINGS frame. NGHTTP2_SETTINGS_ENABLE_PUSH SETTINGS_ENABLE_PUSH NGHTTP2_SETTINGS_HEADER_TABLE_SIZE SETTINGS_HEADER_TABLE_SIZE NGHTTP2_SETTINGS_INITIAL_WINDOW_SIZE SETTINGS_INITIAL_WINDOW_SIZE NGHTTP2_SETTINGS_MAX_CONCURRENT_STREAMS SETTINGS_MAX_CONCURRENT_STREAMS NGHTTP2_SETTINGS_MAX_FRAME_SIZE SETTINGS_MAX_FRAME_SIZE NGHTTP2_SETTINGS_MAX_HEADER_LIST_SIZE SETTINGS_MAX_HEADER_LIST_SIZE NGHTTP2_SETTINGS_TIMEOUT SETTINGS_TIMEOUT NGHTTP2_STREAM_CLOSED STREAM_CLOSED NGHTTP2_STREAM_STATE_CLOSED closed state. NGHTTP2_STREAM_STATE_HALF_CLOSED_LOCAL half closed (local) state. NGHTTP2_STREAM_STATE_HALF_CLOSED_REMOTE half closed (remote) state. NGHTTP2_STREAM_STATE_IDLE idle state. NGHTTP2_STREAM_STATE_OPEN open state. NGHTTP2_STREAM_STATE_RESERVED_LOCAL reserved (local) state. NGHTTP2_STREAM_STATE_RESERVED_REMOTE reserved (remote) state.
