Struct MentionState 

pub struct MentionState { /* private fields */ }

D-fix.6 follow-up: a transient @sent echo on the modeline after a :claude-send pushes context to the agent. Unlike the review badge (a lifecycle span), an at-mention is a momentary event, so the echo is time-boxed: ping() stamps a clear-deadline + wakes the publisher, which shows @sent until the deadline then clears itself (the publisher waits on the wake OR the deadline, whichever comes first).

Implementations

impl MentionState

pub fn new(changed: Arc<Notify>) -> MentionHandle

pub fn ping(&self)

Show @sent for [MENTION_ECHO] from now + wake the publisher.

pub fn remaining(&self) -> Option<Duration>

Time left before the echo clears, or None when it’s inactive/expired. The publisher both renders on this (Some ⇒ show @sent) and sleeps on it to clear the echo when no other wake arrives first.
