Struct ConnectionStatsReader 

pub struct ConnectionStatsReader { /* private fields */ }

A cloneable read handle for the live connection stats of a Reconnect loop.

Obtained via Reconnect::stats. stats returns None while the loop is between connections (reconnecting), and Some snapshot while a session is established.

Implementations

impl ConnectionStatsReader

pub fn presence(&self) -> Presence

Cumulative connects and disconnects of this reconnect loop, the same shape as a relay’s sessions track: sessions - sessions_closed is 1 while connected, and a rate is a delta over any window.

pub fn poll_presence(&mut self, waiter: &Waiter) -> Poll<Result<Presence>>

Poll until either presence counter moves past what this handle last reported.

pub async fn presence_changed(&mut self) -> Result<Presence>

Wait until either presence counter moves past what this handle last reported.

Unlike Reconnect::status, a connect and disconnect that both land before the caller polls are not coalesced away: the counters still moved.

pub fn stats(&self) -> Option<ConnectionStats>

Snapshot the current connection’s stats, or None if not currently connected.

pub fn snapshot(&self) -> Option<ConnectionSnapshot>

Snapshot statistics and protocol together, or None while disconnected.

fn clone_from(&mut self, source: &Self)
