Module retry 

Retry helpers for target-side and server-side rotation steps.

Structs

RetryCfg 🔒

Configuration for the retry helpers.

Enums

GatedOutcome 🔒

The outcome of a with_retries_gated call.

Functions

cap_to_deadline 🔒

Truncate delay so it does not push past deadline, or None once the deadline has passed.

exponential_delay 🔒

base * 2^attempt for a 0-indexed attempt, capped at 32x to avoid overflow.

retry_loop 🔒

The shared retry loop: gate before each try, then op, sleeping between transient failures.

with_retries 🔒

Retry op with exponential backoff. Retry::Permanent returns at once; Retry::Transient retries until the tries run out or deadline passes, with sleeps truncated to it.

with_retries_gated 🔒

Like with_retries, but awaits gate() before every try; an abort returns GatedOutcome::Aborted. Session loss or lease expiry stops target-side steps between tries, never mid-call. Sleeps are not capped to a deadline: the gate checks execute_by before the next try.
