//! Example demonstrating the #[server] blessed preset.
//!
//! `#[server]` = `#[http]` + `#[serve(http)]` in one attribute.
//!
//! ```bash
//! cargo run --example server_preset
//! # Then: curl http://localhost:3000/items
//! # Then: curl -X POST http://localhost:3000/items -H 'Content-Type: application/json' -d '{"name":"widget"}'
//! ```
