Features

Feature	What you get
rate-limit	Fixed-window rate limiting (memory or KvStore).

Overview

When: throttle by IP, user id, or custom key.

Does:

• Fixed-window limits via in-memory or KvStore backend
• Presets: per_minute, login, forgot, …
• Key strategies: IP / identity / custom key_fn

Example

use std::time::Duration;
app.install(RateLimit::new(60, Duration::from_secs(60)));
// or shared store:
app.install(RateLimit::fixed_window(store, 120, Duration::from_secs(60)));

Notes

• Multi-instance: use store / redis + fixed_window

Quick start

In-memory limiter needs no store. Shared (multi-process) uses AppStore:

use std::time::Duration;

app.install(Db::from_env());
app.install(SharedStore::sql(&app)); // or ::redb("./data/kv.redb") / ::redis(&app) / ::memory()
app.install(
    RateLimit::shared(&app, 120, Duration::from_secs(60)).key(RateLimitKey::Identity),
);

Or pass a KvStore explicitly: RateLimit::fixed_window(store, 120, Duration::from_secs(60)).
