HTTP/2.0 error codes.
Error codes are used in RST_STREAM
and GOAWAY
frames to convey the
reasons for the stream or connection error. For example,
SendStream::send_reset
takes a Reason
argument. Also, the Error
type
may contain a Reason
.
Error codes share a common code space. Some error codes apply only to
streams, others apply only to connections, and others may apply to either.
See [RFC 7540] for more information.
See Error Codes in the spec.
The associated condition is not a result of an error.
For example, a GOAWAY might include this code to indicate graceful
shutdown of a connection.
The endpoint detected an unspecific protocol error.
This error is for use when a more specific error code is not available.
The endpoint encountered an unexpected internal error.
The endpoint detected that its peer violated the flow-control protocol.
The endpoint sent a SETTINGS frame but did not receive a response in
a timely manner.
The endpoint received a frame after a stream was half-closed.
The endpoint received a frame with an invalid size.
The endpoint refused the stream prior to performing any application
processing.
Used by the endpoint to indicate that the stream is no longer needed.
The endpoint is unable to maintain the header compression context for
the connection.
The connection established in response to a CONNECT request was reset
or abnormally closed.
The endpoint detected that its peer is exhibiting a behavior that might
be generating excessive load.
The underlying transport has properties that do not meet minimum
security requirements.
The endpoint requires that HTTP/1.1 be used instead of HTTP/2.
