Variants

NoError = 0

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.

ProtocolError = 1

The endpoint detected an unspecific protocol error. This error is for use when a more specific error code is not available.

InternalError = 2

The endpoint encountered an unexpected internal error.

FlowControlError = 3

The endpoint detected that its peer violated the flow-control protocol.

SettingsTimeout = 4

The endpoint sent a SETTINGS frame but did not receive a response in a timely manner. See Section 6.5.3 (“Settings Synchronization”). https://httpwg.org/specs/rfc9113.html#SettingsSync

StreamClosed = 5

The endpoint received a frame after a stream was half-closed.

FrameSizeError = 6

The endpoint received a frame with an invalid size.

RefusedStream = 7

The endpoint refused the stream prior to performing any application processing (see Section 8.7 for details). https://httpwg.org/specs/rfc9113.html#Reliability

Cancel = 8

The endpoint uses this error code to indicate that the stream is no longer needed.

CompressionError = 9

The endpoint is unable to maintain the field section compression context for the connection.

ConnectError = 10

The connection established in response to a CONNECT request (Section 8.5) was reset or abnormally closed. https://httpwg.org/specs/rfc9113.html#CONNECT

EnhanceYourCalm = 11

The endpoint detected that its peer is exhibiting a behavior that might be generating excessive load.

InadequateSecurity = 12

The underlying transport has properties that do not meet minimum security requirements (see Section 9.2). https://httpwg.org/specs/rfc9113.html#TLSUsage

Http1_1Required = 13

The endpoint requires that HTTP/1.1 be used instead of HTTP/2.
