Struct RateLimitLayer 

pub struct RateLimitLayer { /* private fields */ }

Simple in-memory rate limiter (per IP address).

Security note

Uses X-Forwarded-For / X-Real-IP headers to identify clients. These headers can be spoofed unless your reverse proxy (nginx, Cloudflare, etc.) strips and re-sets them. In production, always place this behind a trusted reverse proxy that sets X-Forwarded-For to the real client IP.

For distributed systems, consider a Redis-backed rate limiter instead.

Example

let app = Router::new()
    .route("/api/login", post(login))
    .layer(RateLimitLayer::new(60, Duration::from_secs(60))); // 60 req/min
