Enum EventCursorItem 

#[non_exhaustive]
pub enum EventCursorItem {
    Event(EventEntry),
    Lagged {
        skipped: u64,
    },
}

Available on crate feature std only.

One item EventCursor::poll can hand back: one event-log entry (which may itself still be Segment/Utc-anchored — a cursor sees an entry the instant it is published, not only once it resolves; see EventEntry::anchor), or a loss report.

#[non_exhaustive]: the growth point for anything a cursor might need to surface beyond “entry” or “loss” later, without a breaking change to every match arm in the workspace.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Event(EventEntry)

One event-log entry, in publish order.

Lagged

This cursor fell behind the event log’s ordinary TrunkConfig::event_capacity eviction: skipped entries were evicted before it read them. Exactly SampleCursorItem::Lagged’s contract.

Fields

skipped: u64

Exact count of entries evicted since this cursor’s last successful read.
