Struct JoinRetryPolicy 

pub struct JoinRetryPolicy {
    pub max_attempts: u32,
    pub max_backoff_secs: u64,
}

Tunable retry policy for the join loop.

The schedule is computed by halving from the configured ceiling: for max_attempts = 8 and max_backoff_secs = 32, the per-attempt delays are 0.25 s, 0.5 s, 1 s, 2 s, 4 s, 8 s, 16 s, 32 s — i.e. each delay is max_backoff_secs >> (max_attempts - attempt). This keeps the formula obvious from a single number while preserving exponential growth.

Defaults match the production schedule. Tests construct their own policy with a much smaller max_backoff_secs so the integration suite doesn’t pay a ~minute backoff on every join failure path.

Fields

max_attempts: u32

Number of join attempts before the loop gives up.

max_backoff_secs: u64

Cap on the per-attempt backoff delay, in seconds. The schedule is derived from this ceiling — see the struct doc comment.

Implementations

impl JoinRetryPolicy

pub fn backoff_for(&self, attempt: u32) -> Duration

Backoff delay before attempt (1-indexed). Attempt 0 is the initial try and never sleeps. Returns Duration::ZERO for out-of-range attempts.
