Enum DataStreamResetErrorCode 

#[repr(u64)]
pub enum DataStreamResetErrorCode {
    InternalError = 0,
    Cancelled = 1,
    DeliveryTimeout = 2,
    SessionClosed = 3,
    UnknownObjectStatus = 4,
    TooFarBehind = 5,
    ExcessiveLoad = 9,
    MalformedTrack = 18,
}

Data Stream Reset Error Codes (draft-17, Section 14.5.4).

The registry table is in Section 14.5.4; the per-code descriptions carried on the variants below are the ones given in Section 10.4.3 of the draft.

The table’s last row reserves 0x7f * N + 0x9D for greasing (Section 13). Greasing code points are not a contiguous range and carry no semantics a decoder can act on, so they get no variants and from_u64 rejects them like any other unassigned value.

Variants

InternalError = 0

INTERNAL_ERROR — An implementation specific error.

Cancelled = 1

CANCELLED — The subscriber or publisher cancelled the Request. For Subscriptions, PUBLISH_DONE (Section 9.13) will have a more detailed status code.

DeliveryTimeout = 2

DELIVERY_TIMEOUT — The DELIVERY TIMEOUT Section 9.3.3 was exceeded for this stream.

SessionClosed = 3

SESSION_CLOSED — The publisher session is being closed.

UnknownObjectStatus = 4

UNKNOWN_OBJECT_STATUS — In response to a FETCH, the publisher is unable to determine the Status of the next Object in the requested range.

TooFarBehind = 5

TOO_FAR_BEHIND — The corresponding subscription has exceeded the publisher’s resource limits and is being terminated (see Section 9.3.3).

ExcessiveLoad = 9

EXCESSIVE_LOAD — The publisher is overloaded and is resetting this stream.

MalformedTrack = 18

MALFORMED_TRACK — A relay publisher detected that the track was malformed (see Section 2.4.2).

Implementations

impl DataStreamResetErrorCode

pub const ALL: &[DataStreamResetErrorCode]

Every Data Stream Reset Error Code draft-17 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 — that this is the set from_u64 answers to, and that none of it lands in the range the draft reserves for greasing.

pub fn from_u64(v: u64) -> Option<Self>

Convert a raw u64 to a DataStreamResetErrorCode, if valid.

Returns None for any code draft-17 does not define, including the greasing range. Unknown codes arrive on the wire routinely and are not an error for the decoder.

pub fn as_u64(self) -> u64

Return the raw u64 value of this error code.
