}

Session termination codes, from the table in draft-11 section 3.4 (Termination). Carried in the session-level termination error code.

The draft assigns 0x0 through 0x9 and then 0x10 through 0x15; 0xA through 0xF are not assigned.

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 endpoint breached an agreement, which MAY have been pre-negotiated by the application.

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 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 draft-11 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 message. See session migration, draft-11 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. This includes fields of a stream header or an object header within a data stream. An endpoint that times out waiting for a new object header on an open subgroup stream MAY instead send STOP_SENDING on that stream or terminate the subscription.

AuthTokenCacheOverflow = 19

Auth Token Cache Overflow — the session limit on the total size of all registered authorization tokens has been exceeded. See draft-11 section 8.3.2.3.

DuplicateAuthTokenAlias = 20

Duplicate Auth Token Alias — an Authorization Token attempted to register an alias that was in use. See draft-11 section 8.2.1.1.

VersionNegotiationFailed = 21

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

Implementations

impl SessionErrorCode

pub const ALL: &[SessionErrorCode]

Every session termination code draft-11 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.
