Expand description

What happened on a book feed. See BookFeedStreams.

Aliased Type§

pub enum BookFeedEvent<A = ReceivedAt> {
    Published(BookSnapshot<A>),
    Withdrawn,
    Ended(SnapshotFeedOutcome<FeedError>),
}

Variants§

§

Published(BookSnapshot<A>)

The feed published a snapshot, replacing whatever it served before.

§

Withdrawn

The feed has nothing servable: what it served was withdrawn because nothing was refreshing it. Stop using its data until it publishes again.

§

Ended(SnapshotFeedOutcome<FeedError>)

The feed stopped, and how. Nothing follows it on that feed, which for a SnapshotFeedStream means the stream is over and for a SnapshotFeedStreams means that one label is: the set reads on until its last feed has ended.
