## What it is
A Go library implementing GCRA (leaky bucket) rate limiting on top of Redis, built for the go-redis client. It exposes a simple Allow API with per-second/minute limits and retry-after info, usable in HTTP middleware.

## Use cases
- rate limit API requests per user or project
- implement leaky bucket throttling with Redis
- add rate limiting middleware to a Go HTTP server
- limit how often a job or webhook can run
- return RateLimit-Remaining and Retry-After headers

## When to choose
- you already use go-redis and need distributed rate limiting
- you want GCRA/leaky-bucket semantics without extra dependencies
- you need per-key limits with remaining quota and retry-after values

## When to avoid
- you don't use Redis or want an in-process limiter
- you need token bucket with burst controls rather than GCRA
- your Redis is older than version 3.2

## Facets
