Session Termination Error Codes (draft-15 Section 13.3.1, defined in Section 3.4).

Sent when closing the session. Draft-15 assigns 0x0 through 0x9 and 0x10 through 0x1A; it reserves no greasing range in this registry.

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 9.3.1.2.

GoawayTimeout = 16

GOAWAY_TIMEOUT — the session was closed because the peer took too long to close the session in response to a GOAWAY (Section 9.4) 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 10). 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 9.3.1.4) 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 9.2.1.1).

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 9.2.1.1).

UnknownAuthTokenAlias = 23

UNKNOWN_AUTH_TOKEN_ALIAS — no registered token found for the provided Alias (see Section 9.2.1.1).

ExpiredAuthToken = 24

EXPIRED_AUTH_TOKEN — authorization token has expired (Section 9.2.1.1).

InvalidAuthority = 25

INVALID_AUTHORITY — the specified AUTHORITY does not correspond to this server or cannot be used in this context.

MalformedAuthority = 26

MALFORMED_AUTHORITY — the AUTHORITY value is syntactically invalid.

Implementations

impl SessionErrorCode

pub const ALL: &[SessionErrorCode]

Every session termination code draft-15 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 draft-15 defines it.

pub fn as_u64(self) -> u64

Return the raw u64 value of this error code.
