Struct DiscoveryFailure 

pub struct DiscoveryFailure {
    pub fingerprint: String,
    pub last_attempt_unix: u64,
    pub attempts: u32,
}

One server’s failed boot-discovery record: the launch fingerprint it failed under, when it was last tried (unix seconds) and how many consecutive attempts under that fingerprint failed.

Fields

fingerprint: String

last_attempt_unix: u64

attempts: u32

Implementations

impl DiscoveryFailure

pub fn backoff_secs(&self) -> u64

1 h × 2^(attempts−1), capped at 24 h.

pub fn retry_after_unix(&self) -> u64

Unix second from which the server may be retried.

pub fn suppresses(&self, fingerprint: &str, now_unix: u64) -> bool

Whether boot discovery for a server currently fingerprinting as fingerprint should be skipped at now_unix. A changed fingerprint (config edit) retries immediately; so does a record stamped in the future (the clock moved backwards), rather than stretching the backoff.
