Session termination error codes (draft-23 Section 16.12.1, Table 20).

Sent as the error code when closing the Transport Session. The per-code definitions are in Section 12.2, which also groups 0x200-0x4FF: “Codes from 0x200 to 0x4FF are organized into ranges by category”. See SessionErrorCategory.

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 and no more specific code applies.

InvalidRequestId = 4

INVALID_REQUEST_ID — The endpoint received a Request ID with an incorrect least significant bit for the sender, or a duplicate Request ID. See Section 6.4.2.1.

DuplicateTrackAlias = 5

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

MalformedKeyValue = 6

MALFORMED_KEY_VALUE — A Key-Value-Pair (Figure 4), such as a Setup Option or a Property, has a Value that does not match the definition of its Type.

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 9.1.2.

GoawayTimeout = 16

GOAWAY_TIMEOUT — The session was closed because the peer took too long to close the session in response to a GOAWAY (Section 9.2) message. See session migration (Section 6.6.1).

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 11).

AuthTokenCacheOverflow = 19

AUTH_TOKEN_CACHE_OVERFLOW — The Session limit Section 9.1.3 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 8.9).

MalformedAuthToken = 22

MALFORMED_AUTH_TOKEN — Invalid Auth Token serialization (see Section 8.9).

UnknownAuthTokenAlias = 23

UNKNOWN_AUTH_TOKEN_ALIAS — No registered token found for the provided Alias (see Section 8.9).

ExpiredAuthToken = 24

EXPIRED_AUTH_TOKEN — Authorization token has expired (Section 8.9).

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.

TooManyRequestUpdates = 27

TOO_MANY_REQUEST_UPDATES — The endpoint received a REQUEST_UPDATE that exceeded the per-stream limit communicated via the MAX_REQUEST_UPDATES Setup Option (Section 9.1.7).

InvalidStreamHeader = 512

INVALID_STREAM_HEADER — A data stream or datagram has an unknown type or invalid Type Flags.

MalformedObject = 513

MALFORMED_OBJECT — The serialization of an Object on a data stream or in a datagram cannot be decoded, for example a flag references a prior Object that does not exist.

InvalidObjectStatus = 514

INVALID_OBJECT_STATUS — An Object has an invalid Object Status, or has Properties when its status is not Normal.

TruncatedObject = 515

TRUNCATED_OBJECT — A data stream ended with a FIN in the middle of an Object.

MalformedMessage = 768

MALFORMED_MESSAGE — A control message cannot be parsed or is missing a required element, for example its length does not match its contents.

InvalidField = 769

INVALID_FIELD — A control message was parsed, but a field has a value that is not allowed.

InvalidTrackNamespace = 770

INVALID_TRACK_NAMESPACE — A Track Namespace does not conform to Section 8.7.

UnexpectedMessage = 771

UNEXPECTED_MESSAGE — A control message of an unknown type was received, or a message was received on the wrong stream, in the wrong order, or more times than allowed.

RoleViolation = 772

ROLE_VIOLATION — The peer sent a message or field that is not allowed for its role, for example a server receiving a non-empty New Session URI.

InvalidParameter = 773

INVALID_PARAMETER — A Message Parameter (Section 9.19) is unknown, duplicated, not allowed in the message, or has a value outside its allowed range.

ClosedControlStream = 774

CLOSED_CONTROL_STREAM — The peer closed the control stream (Section 6.3).

DeltaEncodingOverflow = 1_024

DELTA_ENCODING_OVERFLOW — A value decoded from a delta encoding is less than 0 or greater than 2^64 - 1.

FieldLengthExceeded = 1_025

FIELD_LENGTH_EXCEEDED — A field or structure is longer than its maximum allowed length.

Implementations

impl SessionErrorCode

pub const ALL: &[SessionErrorCode]

Every Session Error Code draft-23 assigns, in ascending wire order: the set Self::from_u64 accepts.

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

Convert a raw u64 to a SessionErrorCode, if the draft assigns that code point. None for any unassigned value, including the greasing range.

pub fn as_u64(self) -> u64

Return the raw u64 value of this error code.

pub fn category(self) -> Option<SessionErrorCategory>

The Section 12.2 category of this code, None below 0x200.
