Struct Reason
pub struct Reason(/* private field */);
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.
Implementations
impl Reason
const NO_ERROR: Reason = _;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.
const PROTOCOL_ERROR: Reason = _;The endpoint detected an unspecific protocol error.
This error is for use when a more specific error code is not available.
const INTERNAL_ERROR: Reason = _;The endpoint encountered an unexpected internal error.
const FLOW_CONTROL_ERROR: Reason = _;The endpoint detected that its peer violated the flow-control protocol.
const SETTINGS_TIMEOUT: Reason = _;The endpoint sent a SETTINGS frame but did not receive a response in a timely manner.
const STREAM_CLOSED: Reason = _;The endpoint received a frame after a stream was half-closed.
const FRAME_SIZE_ERROR: Reason = _;The endpoint received a frame with an invalid size.
const REFUSED_STREAM: Reason = _;The endpoint refused the stream prior to performing any application processing.
const CANCEL: Reason = _;Used by the endpoint to indicate that the stream is no longer needed.
const COMPRESSION_ERROR: Reason = _;The endpoint is unable to maintain the header compression context for the connection.
const CONNECT_ERROR: Reason = _;The connection established in response to a CONNECT request was reset or abnormally closed.
const ENHANCE_YOUR_CALM: Reason = _;The endpoint detected that its peer is exhibiting a behavior that might be generating excessive load.
const INADEQUATE_SECURITY: Reason = _;The underlying transport has properties that do not meet minimum security requirements.
const HTTP_1_1_REQUIRED: Reason = _;The endpoint requires that HTTP/1.1 be used instead of HTTP/2.
fn description(&self) -> &strGet a string description of the error code.
