Enum FetchErrorCode 

#[repr(u64)]
pub enum FetchErrorCode {
    InternalError = 0,
    Unauthorized = 1,
    Timeout = 2,
    NotSupported = 3,
    TrackDoesNotExist = 4,

}

FETCH_ERROR codes, from the “FETCH_ERROR Codes” registry in draft-ietf-moq-transport-14 Section 13.1.5. Every row cites Section 9.18 (FETCH_ERROR), the source of the descriptions below.

The draft assigns 0x0 through 0x9, then 0x10 and 0x12; 0x11 is unassigned.

Variants

InternalError = 0

INTERNAL_ERROR — An implementation specific or generic error occurred.

Unauthorized = 1

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

Timeout = 2

TIMEOUT — The fetch could not be completed before an implementation specific timeout. For example, a relay could not FETCH missing objects within the timeout.

NotSupported = 3

NOT_SUPPORTED — The endpoint does not support the FETCH method.

TrackDoesNotExist = 4

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

InvalidRange = 5

INVALID_RANGE — The end of the requested range is earlier than the beginning, the start of the requested range is beyond the Largest Location, or the track has not published any Objects yet.

NoObjects = 6

NO_OBJECTS — No Objects exist between the requested Start and End Locations.

InvalidJoiningRequestId = 7

INVALID_JOINING_REQUEST_ID — The joining Fetch referenced a Request ID that did not belong to an active Subscription.

UnknownStatusInRange = 8

UNKNOWN_STATUS_IN_RANGE — The requested range contains objects with unknown status.

MalformedTrack = 9

MALFORMED_TRACK — A relay publisher detected the track was malformed (see Section 2.5).

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 FetchErrorCode

pub const ALL: &[FetchErrorCode]

Every FETCH_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 FetchErrorCode, if valid.

pub fn as_u64(self) -> u64

Return the raw u64 value of this error code.
