Module rate_limit 

In-memory rate limiting middleware

Fixed window per key (the peer IP by default). State lives in this process, so with several instances each one enforces the limit on its own; put a shared limiter (reverse proxy, Redis) in front for a global limit.

use std::time::Duration;
use ullun::prelude::*;
use ullun::rate_limit::RateLimiter;

App::new()
    .middleware(RateLimiter::new(100, Duration::from_secs(60)))
    .get("/", |_req: Request| async { Ok(Response::text("ok")) })
    .run("127.0.0.1:3000")
    .await
    .unwrap();
