# 快速开始

## 安装Rust

如果您还没有安装Rust，请先按照[官方指南](https://www.rust-lang.org/tools/install)进行安装。

安装完成后，可以通过以下命令验证安装：

```bash
rustc --version
cargo --version
```

## 创建第一个应用

1. 创建一个新的Rust项目：

```bash
cargo new my-app
cd my-app
```

2. 在项目目录中安装Silent：

```bash
cargo add silent
```

3. 在`Cargo.toml`中会自动添加依赖：

```toml
[dependencies]
silent = "2.1.0"
tokio = { version = "1.0", features = ["full"] }
tracing = "0.1"
tracing-subscriber = "0.3"
```

4. 在`src/main.rs`中编写代码：

```rust
use silent::prelude::*;
use tracing::Level;

#[tokio::main]
async fn main() {
    // 初始化日志系统
    tracing_subscriber::fmt()
        .with_max_level(Level::INFO)
        .init();
    
    // 创建路由并定义处理函数
    let route = Route::new("")
        .get(|_req| async { Ok("Hello, World!") });
    
    // 启动服务器
    let server = Server::new();
    println!("Server running at http://127.0.0.1:8000");
    server.run(route).await;
}
```

## 运行应用

```bash
cargo run
```

打开浏览器访问 <http://127.0.0.1:8000> 即可看到"Hello, world!"的响应。
