pub struct RateLimiter { /* private fields */ }

Rate limiter using token bucket algorithm

Implementations

impl RateLimiter

pub fn new(requests_per_minute: u32) -> Self

Create new rate limiter

Arguments

• requests_per_minute - Maximum requests per minute per IP

Example

let limiter = RateLimiter::new(100); // 100 req/min

pub fn with_burst_capacity(self, capacity: u32) -> Self

Set burst capacity (max tokens in bucket)

pub fn with_secure_ip(self, secure: bool) -> Self

Enable secure IP extraction (for use behind proxies)

pub fn check(&self, ip: IpAddr) -> Result<u64, RateLimitError>

Check rate limit for given IP

pub fn bucket_info(&self, ip: IpAddr) -> Option<(u64, u64)>

Get current bucket state for IP

pub fn cleanup(&self, max_age: Duration)

Clear old buckets (cleanup)

pub fn into_layer(self) -> RateLimiterLayer

Convert to tower Layer
