Struct Cadence 

pub struct Cadence { /* private fields */ }

When the next pulse is due.

Due once an interval, and early when the claim changes - a dashboard that learned about a break a minute late would be a minute wrong at exactly the moments it is looked at. A failed attempt holds that back: until the wait is over a change waits too, or a laptop on a train would try again at every pause.

Implementations

impl Cadence

pub fn is_due( &self, now: Instant, state: AgentState, record_missing: bool, ) -> bool

Whether to send now, claiming state.

record_missing is the pulse’s record found empty: nobody has reported since the pulse was turned on, and the person who turned it on is waiting to hear how it went.

pub fn sent(&mut self, now: Instant, state: AgentState, wait: Duration)

Notes a pulse the server took.

pub fn failed(&mut self, now: Instant, wait: Duration)

Notes an attempt that did not arrive; nothing goes before wait is up.
