Redis Backed Rate Limit
This library is inspired by and designed to be compatible with the Upstash Rate Limit library. This means you can have multiple JavaScript and Rust services operate on the same Redis keys and use the same rate limiting algorithms.
Getting Started
Add the dependency
cargo add upstash-ratelimit
Use upstash_ratelimit to
use upstash_ratelimit::{Limiter, RateLimit, Response};
let redis = redis::Client::open("redis://127.0.0.1/")?;
let ratelimit = RateLimit::builder()
.redis(REDIS.clone())
.limiter(Limiter::FixedWindow {
tokens: 30,
window: Duration::from_millis(100),
})
.build()?;
let response = ratelimit.limit("unique-id");
match result {
Response::Success { .. } => println!("Allow!")
Response::Failure { .. } => println!("Rate limited!")
}
Running Unit Tests
Before running cargo test
, spin up a Redis instance on localhost
with docker-compose up -d
. It's a good idea to restart Redis between test runs.
Feature Support
- Single region Redis
- Multi-region Redis
- Fixed window limiting
- Sliding window limiting
- Token bucket limiting
- Cached fixed window limiting
- Arbitrary key prefix
- Ephemeral (in-memory) cache
- Block until ready
- HTTP Redis connection
- This will require substantial effort and should probably reside in a separate library.
- Analytics
- This will require substantial efford and should probably reside in a separate library.
