EventCursor

media_plane::trunk

Struct EventCursor

pub struct EventCursor { /* private fields */ }

Available on crate feature std only.

Expand description

A subscribed reader of a Trunk’s event log. Obtained via Trunk::subscribe_events — read that method’s docs, and Trunk::subscribe’s fan-out guidance, before creating more than a handful of these.

Implementations§

impl EventCursor

pub fn poll(&mut self) -> Option<EventCursorItem>

Pull the next item, if any is ready. Loss is always reported before further data — the same cannot-be-skipped-past precedent as SampleCursor::poll/SegmentCursor::poll.
