HostLoom.RateLimiting

Backend-neutral asynchronous token-bucket rate limiting over System.Threading.RateLimiting.RateLimiter. The package includes an in-process reference store; HostLoom.Redis and HostLoom.Valkey provide shared stores, and HostLoom.RateLimiting.HttpClient integrates outgoing HTTP clients.

var store = new InMemoryRateLimitStore();
var limiter = new DistributedRateLimiter(
    new RateLimitingOptions
    {
        Namespace = "catalog",
        TokenBucket = new TokenBucketRateLimitPolicy
        {
            TokenLimit = 100,
            TokensPerPeriod = 100,
            ReplenishmentPeriod = TimeSpan.FromSeconds(1),
        },
    },
    "catalog-api",
    store);

using var lease = await limiter.AcquireAsync(cancellationToken: stoppingToken);
if (!lease.IsAcquired)
{
    // Inspect MetadataName.RetryAfter before scheduling independent work.
}

AcquireAsync is the supported acquisition operation. AttemptAcquire returns a conservative failed lease without store I/O so hosts such as ASP.NET Core can fall back to asynchronous acquisition. Token-bucket leases do not refund permits on disposal.

The store receives fully prefixed {namespace}:rate:{key} keys. A rejected lease can contain MetadataName.RetryAfter and RateLimitMetadata.RemainingPermits. Store failure is different from quota exhaustion: OnUnavailable = Deny (the default) returns unavailable metadata, while explicit Allow admits work with degraded metadata. Caller cancellation propagates, and an ambiguous backend result is never replayed or refunded.

Every instance using the same namespace and key must use the same token-bucket policy. Redis and Valkey replication is asynchronous, so failover can lose recently consumed tokens; this is shared coordination, not an absolute quota guarantee during failover.
