Rulvar API reference / @rulvar/core / quotaRuleAdmission

Function: quotaRuleAdmission()

function quotaRuleAdmission(
   rule, 
   counters, 
   estimate, 
   msUntilWindowEnd): 
  | {
  admit: true;
}
  | {
  admit: false;
  reason: string;
  retryAfterMs: number;
};

Defined in: packages/core/src/model/quota.ts:275

One rule's admission verdict against its current-window counters, the pure decision both reference implementations share. A denial carries the window remainder as retryAfterMs, except when the estimate alone can never fit the token cap: that denial says retryAfterMs 0 (retry immediately), so the caller's bounded attempts exhaust without waiting and failover gets its chance.

Parameters

Parameter	Type
rule	QuotaRule
counters	QuotaCounters
estimate	QuotaCounters
msUntilWindowEnd	number

Returns

| { admit: true; } | { admit: false; reason: string; retryAfterMs: number; }
