pub struct Reason(u32);
Expand description

HTTP/2 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.

Implementations

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.
