Module rate_limit

Expand description

Provider-neutral quota, rate-limit, and retry-delay domains.

Structs§

DelayDecision: Pure bounded delay decision. The caller owns sleeping and clock acquisition.
DelaySeconds: A relative delay measured in whole seconds.
HttpDate: A parsed HTTP date represented as signed Unix seconds.
QuotaBucket: One coherent provider quota bucket.
QuotaBucketId: Provider-defined quota bucket identity in fixed-capacity storage.
QuotaBuckets: Fixed-capacity set of distinct provider quota buckets.
QuotaDelayPolicy: Caller-owned quota delay policy.
QuotaExtension: Bounded informational quota extension.
RateLimit: Legacy single-bucket rate-limit metadata.
WallClockTimestamp: An absolute Unix wall-clock timestamp in whole seconds.

DelayConflictPolicy: Conflict policy when Retry-After and exhausted quota buckets disagree.
DelayDecisionError: Failure to derive an unambiguous bounded delay.
DelaySource: Metadata source selected for a delay decision.
ExcessDelayPolicy: Handling for a computed delay above the caller’s maximum.
PastTimestampPolicy: Handling for timestamps at or before the caller’s observation time.
QuotaError: Invalid quota bucket or bounded collection.
QuotaExtensionError: Invalid informational quota extension.
QuotaReset: Reset semantics for one provider quota bucket.
RateLimitError: Rate-limit metadata validation error.
RetryAfter: Standard HTTP Retry-After value.
RetryAfterError: Invalid Retry-After syntax or value.

MAX_QUOTA_BUCKETS: Maximum provider quota buckets retained from one response.
MAX_QUOTA_BUCKET_ID_BYTES: Maximum exact-byte provider quota bucket identity length.
MAX_QUOTA_EXTENSIONS_PER_BUCKET: Maximum informational extensions retained per quota bucket.
MAX_QUOTA_EXTENSION_NAME_BYTES: Maximum exact-byte quota extension name length.
MAX_QUOTA_EXTENSION_VALUE_BYTES: Maximum exact-byte quota extension value length.
