Enum FetchErrorCode 

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

FETCH_ERROR codes (draft-10, Section 8.14 “FETCH_ERROR”).

Draft-10 is internally inconsistent about this registry, and the variants below follow the table rather than the prose. Section 8.12 states that a publisher MUST return FETCH_ERROR with error code No Objects when the requested start is past the latest published group, and Section 8.12.1 states the same for a joining fetch against a track with no published content. Neither the table in Section 8.14 nor any other table in draft-10 assigns No Objects a number, so it cannot be represented here and a peer that sends it has no value this draft could have told it to use. Draft-11 is the first to assign the code, as 0x6, which is where it has stayed since.

Implementations

impl FetchErrorCode

pub const ALL: &[FetchErrorCode]

Every FETCH_ERROR code draft-10 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 draft-10 defines it.

pub fn as_u64(self) -> u64

Return the raw u64 value of this error code.
