Enum SubscribeErrorCode 

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

SUBSCRIBE_ERROR codes (draft-12 section 8.9).

The table assigns 0x0 through 0x5, then 0x10 and 0x12; 0x11 is unassigned. The session termination table carries three auth-token codes at 0x16, 0x17 and 0x18, exactly 6 above 0x10, 0x11 and 0x12, so the unassigned slot lines up with Unknown Auth Token Alias, which has no request-level counterpart. The draft does not say this is why the gap is there.

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 8.2.1.1).

ExpiredAuthToken = 18

Expired Auth Token — Authorization token has expired (see section 8.2.1.1).

Implementations

impl SubscribeErrorCode

pub const ALL: &[SubscribeErrorCode]

Every SUBSCRIBE_ERROR code draft-12 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 SubscribeErrorCode, if valid.

pub fn as_u64(self) -> u64

Return the raw u64 value of this error code.
