QUIC error codes sent on the wire.

As defined in RFC9000.

Variants

NoError = 0

An endpoint uses this with CONNECTION_CLOSE to signal that the connection is being closed abruptly in the absence of any error.

InternalError = 1

The endpoint encountered an internal error and cannot continue with the connection.

ConnectionRefused = 2

The server refused to accept a new connection.

FlowControlError = 3

An endpoint received more data than it permitted in its advertised data limits; see Section 4.

StreamLimitError = 4

An endpoint received a frame for a stream identifier that exceeded its advertised stream limit for the corresponding stream type.

StreamStateError = 5

An endpoint received a frame for a stream that was not in a state that permitted that frame.

FinalSizeError = 6

(1) An endpoint received a STREAM frame containing data that exceeded the previously established final size, (2) an endpoint received a STREAM frame or a RESET_STREAM frame containing a final size that was lower than the size of stream data that was already received, or (3) an endpoint received a STREAM frame or a RESET_STREAM frame containing a different final size to the one already established.

FrameEncodingError = 7

An endpoint received a frame that was badly formatted – for instance, a frame of an unknown type or an ACK frame that has more acknowledgment ranges than the remainder of the packet could carry.

TransportParameterError = 8

An endpoint received transport parameters that were badly formatted, included an invalid value, omitted a mandatory transport parameter, included a forbidden transport parameter, or were otherwise in error.

ConnectionIdLimitError = 9

An endpoint received transport parameters that were badly formatted, included an invalid value, omitted a mandatory transport parameter, included a forbidden transport parameter, or were otherwise in error.

ProtocolViolation = 10

An endpoint detected an error with protocol compliance that was not covered by more specific error codes.

InvalidToken = 11

A server received a client Initial that contained an invalid Token field.

ApplicationError = 12

The application or application protocol caused the connection to be closed.

CryptoBufferExceeded = 13

An endpoint has received more data in CRYPTO frames than it can buffer.

KeyUpdateError = 14

An endpoint detected errors in performing key updates.

AeadLimitReached = 15

An endpoint has reached the confidentiality or integrity limit for the AEAD algorithm used by the given connection.

NoViablePath = 16

An endpoint has determined that the network path is incapable of supporting QUIC. An endpoint is unlikely to receive a CONNECTION_CLOSE frame carrying this code except when the path does not support a large enough MTU.

Trait Implementations

impl Clone for WireErrorCode

fn clone(&self) -> WireErrorCode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WireErrorCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for WireErrorCode

fn eq(&self, other: &WireErrorCode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
