Struct HybridRateLimiter 

pub struct HybridRateLimiter { /* private fields */ }

Hybrid rate limiter with in-memory fast path and periodic DB sync.

Per-user/per-IP checks use a local DashMap for sub-microsecond decisions. Global keys always hit the database for strict cross-node consistency.

Implementations

impl HybridRateLimiter

pub fn new(pool: PgPool) -> Self

pub async fn check( &self, bucket_key: &str, config: &RateLimitConfig, ) -> Result<RateLimitResult>

Check rate limit. Uses local fast path for per-user/per-IP keys, database for global keys.

pub fn build_key( &self, key_type: RateLimitKey, action_name: &str, auth: &AuthContext, request: &RequestMetadata, ) -> String

pub async fn enforce( &self, bucket_key: &str, config: &RateLimitConfig, ) -> Result<RateLimitResult>

pub fn cleanup_local(&self, max_idle: Duration)

Clean up expired local buckets (call periodically).
