Struct RetryPolicy 

pub struct RetryPolicy {
    pub max_attempts: u32,
    pub backoff: Duration,
    pub give_up_after: Duration,
    pub request_deadline: Option<Duration>,
    pub idempotent: bool,
}

Reconnect-and-resubmit policy for retryable errors (handoff, host restart).

Fields

max_attempts: u32

backoff: Duration

give_up_after: Duration

Give up after this long regardless of attempts. Not a request timeout: a single call may run as long as the host keeps it alive.

request_deadline: Option<Duration>

Per-attempt connect + request deadline (None = unbounded).

idempotent: bool

The request is safe to run twice. When false (the default) a request is resubmitted only if the host provably did not run it (service unavailable at connect, or an explicit host handoff); a connection that closed after the request was written is returned as-is, and a timeout is returned as-is. When true, a connection that closed after the write and a timeout are resubmitted too.
