}

Session termination codes (draft-13 Section 3.4, Termination).

Sent in the QUIC CONNECTION_CLOSE frame or the WebTransport CLOSE_WEBTRANSPORT_SESSION capsule. Draft-13: “When terminating the Session, the application MAY use any error message and SHOULD use a relevant code, as defined below”.

The table assigns 0x0 through 0x9 and 0x10 through 0x18. 0xA through 0xF are unassigned.

Variants

NoError = 0

No Error — The session is being terminated without an error.

InternalError = 1

Internal Error — An implementation specific error occurred.

Unauthorized = 2

Unauthorized — The client is not authorized to establish a session.

ProtocolViolation = 3

Protocol Violation — The remote endpoint performed an action that was disallowed by the specification.

InvalidRequestId = 4

Invalid Request ID — The session was closed because the endpoint used a Request ID that was smaller than or equal to a previously received request ID, or the least-significant bit of the request ID was incorrect for the endpoint.

DuplicateTrackAlias = 5

Duplicate Track Alias — The endpoint attempted to use a Track Alias that was already in use.

KeyValueFormattingError = 6

Key-Value Formatting Error — the key-value pair has a formatting error.

TooManyRequests = 7

Too Many Requests — The session was closed because the endpoint used a Request ID equal to or larger than the current Maximum Request ID.

InvalidPath = 8

Invalid Path — The PATH parameter was used by a server, on a WebTransport session, or the server does not support the path.

MalformedPath = 9

Malformed Path — The PATH parameter does not conform to the rules in Section 8.3.2.1.

GoawayTimeout = 16

GOAWAY Timeout — The session was closed because the peer took too long to close the session in response to a GOAWAY (Section 8.4) message. See session migration (Section 3.5).

ControlMessageTimeout = 17

Control Message Timeout — The session was closed because the peer took too long to respond to a control message.

DataStreamTimeout = 18

Data Stream Timeout — The session was closed because the peer took too long to send data expected on an open Data Stream (see Section 9). This includes fields of a stream header or an object header within a data stream. If an endpoint times out waiting for a new object header on an open subgroup stream, it MAY send a STOP_SENDING on that stream or terminate the subscription.

AuthTokenCacheOverflow = 19

Auth Token Cache Overflow — the Session limit Section 8.3.2.3 of the size of all registered Authorization tokens has been exceeded.

DuplicateAuthTokenAlias = 20

Duplicate Auth Token Alias — Authorization Token attempted to register an Alias that was in use (see Section 8.2.1.1).

VersionNegotiationFailed = 21

Version Negotiation Failed — The client didn’t offer a version supported by the server.

MalformedAuthToken = 22

Malformed Auth Token — Invalid Auth Token serialization during registration (see Section 8.2.1.1).

UnknownAuthTokenAlias = 23

Unknown Auth Token Alias — No registered token found for the provided Alias (see Section 8.2.1.1).

ExpiredAuthToken = 24

Expired Auth Token — Authorization token has expired Section 8.2.1.1).

Implementations

impl SessionErrorCode

pub const ALL: &[SessionErrorCode]

Every session termination code draft-13 assigns, in ascending wire order.

This is the set Self::from_u64 accepts, written out so that it can be enumerated: nothing can iterate an enum’s variants, so a caller that wants the registry has to be handed it. Writing it down is also what lets a test state its claims about the registry itself rather than about the range some sweep happens to reach.

pub fn from_u64(v: u64) -> Option<Self>

Convert a raw u64 to a SessionErrorCode, if valid.

pub fn as_u64(self) -> u64

Return the raw u64 value of this error code.
