Limiter

Create a new limiter wrapper.

Get the underlying rate limiter store.

Atomically consume capacity from an admission policy.

Consume a group, returning decisions through the first denied policy.

Groups are atomic except on Redis Cluster, where a concurrent denial during consumption may leave earlier policies charged.

Atomically extend a cooldown block.

Inspect a policy without mutating its state.

Execute a callback when the policy allows it.

Record a failure against a backoff policy.

Clear the state for an identically parameterized policy.

Validate admission constraints shared by every store.

Validate a fixed-window policy and return its maximum state duration.

Validate a sliding-window policy and return its maximum state duration.

Validate a leaky-bucket policy and return its maximum state duration.

Ensure current-time arithmetic fits every first-party store.

Resolve the physical state key for a policy.

Create an unlimited admission result.
