## 🚀 **Getting Started**
### **Installation**
```toml
[dependencies]
rust-rabbit = "0.1.0"
tokio = { version = "1.0", features = ["full"] }
serde = { version = "1.0", features = ["derive"] }
```
### **Quick Example**
```rust
use rust_rabbit::{RustRabbit, RabbitConfig};
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
// Builder pattern configuration
let config = RabbitConfig::builder()
.connection_string("amqp://localhost:5672")
.retry(|retry| retry.aggressive())
.health(|health| health.frequent())
.pool(|pool| pool.high_throughput())
.build();
let rabbit = RustRabbit::new(config).await?;
let publisher = rabbit.publisher();
// Publish with builder options
let options = rust_rabbit::PublishOptions::builder()
.durable()
.auto_declare_queue()
.build();
publisher.publish_to_queue("orders", &message, Some(options)).await?;
Ok(())
}
```
