Struct TaggedEvent 

pub struct TaggedEvent {
    pub now: Instant,
    pub event: Event,
}

An Event together with the instant its condition was observed at.

The agent’s events are produced inside handle_read / handle_timeout / close, all of which know the time, but they are consumed from poll_event, which does not. Carrying the instant in the payload means the consumer is told when the condition happened rather than having to retain an instant of its own and guess — the same channel TaggedBytesMut already provides on the read path.

Fields

now: Instant

When the condition this event reports was observed.

event: Event

The event itself.
