func GuardAction ¶

func GuardAction(ledger cost.Reserver, estimateMicros int64) action.AnyHook

GuardAction integrates any cost.Reserver with a Kernel action. The adapter reserves before execution, releases on failure/cancel/panic, and records a successful reported cost. Terminal accounting is deliberately isolated from the request context: Commit and Release use a fresh background context with a five-second timeout, so a canceled request cannot strand a distributed reservation. Applications that need terminal errors returned to their caller should use cost.Reserver directly rather than a void hook.
