# ruststream-fred
Redis / Valkey broker implementation for the [RustStream](../..) messaging framework, backed by
[`fred`](https://crates.io/crates/fred). Built on Redis Streams: durable consumer groups with
acknowledgement, redelivery, and crash recovery, across standalone, cluster, and sentinel
topologies.
## Testing
```toml
[dev-dependencies]
ruststream-fred = { version = "*", features = ["testing"] }
```
`features = ["testing"]` exposes an in-memory test client (a handler-stub dispatcher with exact
stream-key routing). Never enable this feature in production builds.
