Enum RequestErrorCode 

#[repr(u64)]
pub enum RequestErrorCode {
    InternalError = 0,
    Unauthorized = 1,
    Timeout = 2,
    NotSupported = 3,
    TrackDoesNotExist = 4,
    InvalidRange = 5,
    MalformedAuthToken = 16,
    ExpiredAuthToken = 18,
}

SUBSCRIBE_ERROR codes, from the “SUBSCRIBE_ERROR Codes” registry in draft-ietf-moq-transport-14 Section 13.1.2. Every row cites Section 9.9 (SUBSCRIBE_ERROR), the source of the descriptions below.

This type decodes SUBSCRIBE_ERROR only. It is not a shared request-level registry: draft-14 gives each request-scoped message its own registry, and they disagree at 0x4. Decoding another message’s error code with this type silently produces the wrong variant.

code	SUBSCRIBE_ERROR	PUBLISH_ERROR	FETCH_ERROR	ANNOUNCE_ERROR	SUBSCRIBE_NAMESPACE_ERROR
0x4	TRACK_DOES_NOT_EXIST	UNINTERESTED	TRACK_DOES_NOT_EXIST	UNINTERESTED	NAMESPACE_PREFIX_UNKNOWN

Use PublishErrorCode, FetchErrorCode, AnnounceErrorCode and SubscribeNamespaceErrorCode for those messages.

The name is RequestErrorCode for compatibility with existing callers; the registry it transcribes is SUBSCRIBE_ERROR.

Variants

InternalError = 0

INTERNAL_ERROR — An implementation specific or generic error occurred.

Unauthorized = 1

UNAUTHORIZED — The subscriber is not authorized to subscribe to the given track.

Timeout = 2

TIMEOUT — The subscription could not be completed before an implementation specific timeout. For example, a relay could not establish an upstream subscription within the timeout.

NotSupported = 3

NOT_SUPPORTED — The endpoint does not support the SUBSCRIBE method.

TrackDoesNotExist = 4

TRACK_DOES_NOT_EXIST — The requested track is not available at the publisher.

InvalidRange = 5

INVALID_RANGE — The end of the SUBSCRIBE range is earlier than the beginning, or the end of the range has already been published.

MalformedAuthToken = 16

MALFORMED_AUTH_TOKEN — Invalid Auth Token serialization during registration (see Section 9.2.1.1).

ExpiredAuthToken = 18

EXPIRED_AUTH_TOKEN — Authorization token has expired (Section 9.2.1.1).

Implementations

impl RequestErrorCode

pub const ALL: &[RequestErrorCode]

Every SUBSCRIBE_ERROR code draft-14 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 RequestErrorCode, if valid.

pub fn as_u64(self) -> u64

Return the raw u64 value of this error code.
