Enum FetchErrorCode 

#[repr(u64)]
pub enum FetchErrorCode {
    InternalError = 0,
    Unauthorized = 1,
    Timeout = 2,
    NotSupported = 3,
    TrackDoesNotExist = 4,
    InvalidRange = 5,
    NoObjects = 6,
    InvalidJoiningSubscribeId = 7,
    MalformedAuthToken = 16,
    UnknownAuthTokenAlias = 17,
    ExpiredAuthToken = 18,
}

FETCH_ERROR codes, from the table in draft-11 section 8.15.

The draft assigns 0x0 through 0x7 and then 0x10 through 0x12; 0x8 through 0xF are not assigned.

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 Object, or the track has not published any Objects yet.

NoObjects = 6

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

InvalidJoiningSubscribeId = 7

Invalid Joining Subscribe ID — the joining Fetch referenced a Request ID that did not belong to an active Subscription.

MalformedAuthToken = 16

Malformed Auth Token — invalid Auth Token serialization during registration. See draft-11 section 8.2.1.1.

UnknownAuthTokenAlias = 17

Unknown Auth Token Alias — the Authorization Token refers to an alias that is not registered. See draft-11 section 8.2.1.1.

ExpiredAuthToken = 18

Expired Auth Token — the authorization token has expired. See draft-11 section 8.2.1.1.

Implementations

impl FetchErrorCode

pub const ALL: &[FetchErrorCode]

Every FETCH_ERROR 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 FetchErrorCode, if valid.

pub fn as_u64(self) -> u64

Return the raw u64 value of this error code.
