Enum SubscribeErrorCode 

#[repr(u64)]
pub enum SubscribeErrorCode {
    InternalError = 0,
    Unauthorized = 1,
    Timeout = 2,
    NotSupported = 3,
    TrackDoesNotExist = 4,
    InvalidRange = 5,
    RetryTrackAlias = 6,
}

SUBSCRIBE_ERROR codes, from draft-09 Section 7.16 (SUBSCRIBE_ERROR).

The draft introduces the table with “The application SHOULD use a relevant error code in SUBSCRIBE_ERROR, as defined below”.

Variants

InternalError = 0

Internal Error.

Unauthorized = 1

Unauthorized.

Timeout = 2

Timeout.

NotSupported = 3

Not Supported.

TrackDoesNotExist = 4

Track Does Not Exist.

InvalidRange = 5

Invalid Range — Section 7.4 adds that if a publisher cannot satisfy the requested start or end, or if the end has already been published, it SHOULD send a SUBSCRIBE_ERROR with this code.

RetryTrackAlias = 6

Retry Track Alias — Section 7.16 adds that the subscriber SHOULD re-issue the SUBSCRIBE with the Track Alias carried in the SUBSCRIBE_ERROR message instead. If that Track Alias is already in use, the subscriber MUST close the connection with a Duplicate Track Alias error (Section 3.5).

Implementations

impl SubscribeErrorCode

pub const ALL: &[SubscribeErrorCode]

Every SUBSCRIBE_ERROR code draft-09 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 draft-09 defines it.

pub fn as_u64(self) -> u64

Return the raw u64 value of this error code.
