Struct RequestRateLimiter 

pub struct RequestRateLimiter { /* private fields */ }

An exact sliding-window limiter with bounded per-host state.

Host names are hashed with a per-instance random key and never retained. Hash collisions can only make admission stricter. Callers should pass the canonical host so aliases do not receive separate windows.

Implementations

impl RequestRateLimiter

pub fn new(config: RateLimitConfig) -> Result<Self, RateLimitConfigError>

pub fn check(&self, canonical_host: &str, now: Instant) -> RateLimitDecision

Atomically admits and records one request, or reports the limiting window and the earliest useful retry time.

pub fn tracked_hosts(&self) -> usize
