## 🔧 Installation

### Prerequisites

- Rust 1.70 or later
- HDC server must be installed and running
- A HarmonyOS/OpenHarmony device connected via USB or network

### Add to Your Project

Add this to your `Cargo.toml`:

```toml
[dependencies]
hdc-rs = "0.1"
tokio = { version = "1", features = ["full"] }
```

### Feature Flags

- `blocking` - Enable synchronous/blocking API for FFI bindings

```toml
[dependencies]
hdc-rs = { version = "0.1", features = ["blocking"] }
```

## 🚀 Quick Start

### Async API (Recommended)

```rust
use hdc_rs::HdcClient;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Connect to HDC server
    let mut client = HdcClient::connect("127.0.0.1:8710").await?;
    
    // List connected devices
    let devices = client.list_targets().await?;
    println!("Devices: {:?}", devices);
    
    if devices.is_empty() {
        println!("No devices connected!");
        return Ok(());
    }
    
    // Select and connect to first device
    client.connect_device(&devices[0]).await?;
    println!("Connected to device: {}", devices[0]);
    
    // Execute shell command on the selected device
    let output = client.shell("ls -l /data").await?;
    println!("Output:\n{}", output);
    
    Ok(())
}
```

### Blocking API (for FFI/PyO3)

Enable the `blocking` feature for synchronous API:

```toml
[dependencies]
hdc-rs = { version = "0.1", features = ["blocking"] }
```

```rust
use hdc_rs::blocking::HdcClient;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Connect to HDC server (synchronous!)
    let mut client = HdcClient::connect("127.0.0.1:8710")?;
    
    // List connected devices
    let devices = client.list_targets()?;
    println!("Devices: {:?}", devices);
    
    if !devices.is_empty() {
        // Connect and execute command
        client.connect_device(&devices[0])?;
        let output = client.shell("uname -a")?;
        println!("Output: {}", output);
    }
    
    Ok(())
}
```

  - Useful for real-time log monitoring

### Usage Pattern

**Option 1: Select device first (Recommended)**
```rust
let mut client = HdcClient::connect("127.0.0.1:8710").await?;
let devices = client.list_targets().await?;

// Connect to device - this re-establishes connection with device ID in handshake
client.connect_device(&devices[0]).await?;

// Now shell commands will be routed to the selected device
let output = client.shell("ls /data").await?;
```

**Option 2: Specify device per command**
```rust
let mut client = HdcClient::connect("127.0.0.1:8710").await?;
let devices = client.list_targets().await?;

// Execute on specific device without selecting
let output = client.shell_on_device(&devices[0], "ls /data").await?;
```

**Option 3: Port forwarding**
```rust
use hdc_rs::{HdcClient, ForwardNode};

let mut client = HdcClient::connect("127.0.0.1:8710").await?;
let devices = client.list_targets().await?;
client.connect_device(&devices[0]).await?;

// Forward local TCP 8080 to device TCP 8081
client.fport(ForwardNode::Tcp(8080), ForwardNode::Tcp(8081)).await?;

// List all forwards
let tasks = client.fport_list().await?;
for task in tasks {
    println!("Forward: {}", task);
}

// Remove forward
client.fport_remove("tcp:8080 tcp:8081").await?;
```

**Option 4: App management**
```rust
use hdc_rs::{HdcClient, InstallOptions, UninstallOptions};

let mut client = HdcClient::connect("127.0.0.1:8710").await?;
let devices = client.list_targets().await?;
client.connect_device(&devices[0]).await?;

// Install app (replace if exists)
let opts = InstallOptions::new().replace(true);
client.install(&["app.hap"], opts).await?;

// Uninstall app (keep data)
let opts = UninstallOptions::new().keep_data(true);
client.uninstall("com.example.app", opts).await?;
```

**Option 5: Device logs (hilog)**
```rust
use hdc_rs::HdcClient;

let mut client = HdcClient::connect("127.0.0.1:8710").await?;
let devices = client.list_targets().await?;
client.connect_device(&devices[0]).await?;

// Get logs as buffered string
let logs = client.hilog(Some("-t app")).await?;
println!("App logs:\n{}", logs);

// Stream logs continuously
client.hilog_stream(None, |log_chunk| {
   

**Option 6: Monitor device connections**
```rust
use hdc_rs::HdcClient;
use std::time::Duration;

let mut client = HdcClient::connect("127.0.0.1:8710").await?;

// Wait for any device to connect (blocks until a device is available)
let device = client.wait_for_device().await?;
println!("Device connected: {}", device);

// Monitor device list changes in real-time
client.monitor_devices(Duration::from_secs(2), |devices| {
    println!("Device list updated: {} device(s)", devices.len());
    for device in devices {
        println!("  - {}", device);
    }
    true // Continue monitoring, return false to stop
}).await?;
```

**Option 7: File transfer**
```rust
use hdc_rs::{HdcClient, FileTransferOptions};

let mut client = HdcClient::connect("127.0.0.1:8710").await?;
let devices = client.list_targets().await?;
client.connect_device(&devices[0]).await?;

// Send file to device with options
let opts = FileTransferOptions::new()
    .hold_timestamp(true)   // Preserve timestamp
    .compress(true);         // Compress transfer
client.file_send("local.txt", "/data/local/tmp/remote.txt", opts).await?;

// Receive file from device
let opts = FileTransferOptions::new().sync_mode(true);
client.file_recv("/data/local/tmp/remote.txt", "local.txt", opts).await?;
``` print!("{}", log_chunk);
    true // Continue streaming, return false to stop
}).await?;
```

### Error Handling

All methods return `Result<T, HdcError>`. The library provides comprehensive error types:

```rust
use hdc_rs::{HdcClient, HdcError};

match client.shell("ls").await {
    Ok(output) => println!("{}", output),
    Err(HdcError::NotConnected) => eprintln!("Not connected to HDC server!"),
    Err(HdcError::Timeout) => eprintln!("Command timeout!"),
    Err(HdcError::DeviceNotFound) => eprintln!("Device not found!"),
    Err(HdcError::ProtocolError(msg)) => eprintln!("Protocol error: {}", msg),
    Err(e) => eprintln!("Error: {}", e),
}
```

**Available Error Types:**
- `NotConnected` - Not connected to HDC server
- `Timeout` - Operation timeout
- `DeviceNotFound` - Target device not found
- `ProtocolError` - Protocol-level error
- `IoError` - I/O error (network, file, etc.)
- `InvalidResponse` - Invalid server response
- `CommandFailed` - Command execution failed

## 🐛 Troubleshooting

### Common Issues

#### "No devices found"

**Solution:**
- Ensure HDC server is running: `hdc start`
- Check device connection: `hdc list targets`
- Verify device is authorized (check device screen for authorization prompt)
- For network devices: `hdc tconn <device_ip>:5555`

#### Connection timeout

**Symptoms:** `HdcError::Timeout` or connection hangs

**Solution:**
- Check if HDC server is listening on port 8710:
  - Windows: `netstat -ano | findstr 8710`
  - Linux/macOS: `netstat -an | grep 8710` or `lsof -i :8710`
- Restart HDC server: `hdc kill` then `hdc start`
- Check firewall settings

#### Protocol errors

**Symptoms:** `HdcError::ProtocolError` or unexpected responses

**Solution:**
- Ensure HDC server version compatibility (tested with 3.2.0+)
- Check server version: `hdc version` or `client.check_server().await?`
- Update HDC server to the latest version
- Enable debug logging to inspect protocol messages

#### File transfer fails

**Symptoms:** `HdcError::IoError` during file operations

**Solution:**
- Verify file paths are correct
- Check device storage permissions
- Ensure target directory exists on device
- For large files, increase timeout or use compression

#### "Device not authorized"

**Solution:**
- Check device for authorization dialog
- Revoke and re-authorize: `hdc kill-server` then reconnect device
- Check device developer options are enabled

### Debug Tips

1. **Enable verbose logging:**
   ```bash
   RUST_LOG=hdc_rs=trace cargo run --example your_example
   ```

2. **Use the comprehensive example:**
   ```bash
   cargo run --example comprehensive
   ```

3. **Check HDC server logs:**
   - Server logs are typically in the HDC installation directory
   - Use `hdc -l 5` for verbose HDC logging

4. **Test with official HDC client:**
   ```bash
   hdc list targets
   hdc shell ls /data
   ```
   If the official client works but hdc-rs doesn't, please file an issue.

## 📊 Performance

- **Zero-copy parsing** with `bytes` crate
- **Async I/O** with Tokio for efficient concurrency
- **Connection pooling** support (reuse connections)
- **Streaming support** for large file transfers and log streaming

### Benchmarks

Typical performance on a modern system:

- Device listing: ~10-50ms
- Shell command: ~20-100ms (depends on command)
- File transfer: ~10-50 MB/s (depends on USB/network speed and device)

## 🗺️ Roadmap

### Current Status (v0.1.0)

- ✅ TCP connection management
- ✅ Async/await API
- ✅ Blocking API for FFI
- ✅ Device management (list, connect, monitor)
- ✅ Shell command execution
- ✅ File transfer (send/recv)
- ✅ Port forwarding (TCP, Unix sockets, JDWP, Ark)
- ✅ App management (install/uninstall)
- ✅ Log streaming (hilog)
- ✅ Python bindings (PyO3)
