Struct phron_finality::sync_oracle::SyncOracle

pub struct SyncOracle {
    last_far_behind: Arc<Mutex<Instant>>,
    last_update: Arc<Mutex<Instant>>,
}

A sync oracle implementation tracking how recently the node was far behind the highest known justification. It defines being in major sync as being more than 15 blocks behind the highest known justification less than 10 seconds ago. It defines being offline as not getting any update for at least 6 seconds (or never at all).

Fields

last_far_behind: Arc<Mutex<Instant>>

last_update: Arc<Mutex<Instant>>
