The OpenPanel Rust SDK allows you to track user behavior in your Rust applications. This guide provides instructions for installing and using the Rust SDK in your project.

<Callout>
View the [Rust SDK on GitHub](https://github.com/tstaetter/openpanel-rust-sdk/) for the latest updates and source code.

## Installation

<Steps>
### Install dependencies

Add the following to your `Cargo.toml`:

```toml
[dependencies]
openpanel-sdk = "0.1.0"
```

Or install via cargo:

```bash
cargo add openpanel-sdk
```

### Set environment variables

Set your environment variables in a `.env` file:

```bash
OPENPANEL_TRACK_URL=https://api.openpanel.dev/track
OPENPANEL_CLIENT_ID=<YOUR_CLIENT_ID>
OPENPANEL_CLIENT_SECRET=<YOUR_CLIENT_SECRET>
```

### Initialize

Import and initialize the OpenPanel SDK:

```rust
use openpanel_sdk::sdk::Tracker;

let tracker = Tracker::try_new_from_env()?.with_default_headers()?;
```

### Configuration Options

<CommonSdkConfig />

</Steps>

## Usage

### Tracking Events

To track an event, use the `track` method:

```rust
use std::collections::HashMap;
use openpanel_sdk::sdk::Tracker;

let mut properties = HashMap::new();
properties.insert("name".to_string(), "rust".to_string());

let response = tracker
    .track("test_event".to_string(), Some(properties), None)
    .await?;
```

### Identifying Users

To identify a user, you need to convert your user struct into `user::IdentifyUser` by implementing the `From` trait:

```rust
use std::collections::HashMap;
use openpanel_sdk::sdk::Tracker;
use openpanel_sdk::user;

struct Address {
    pub street: String,
    pub city: String,
    pub zip: String,
}

struct AppUser {
    pub id: String,
    pub email: String,
    pub first_name: String,
    pub last_name: String,
    pub address: Address,
}

impl From<Address> for HashMap<String, String> {
    fn from(address: Address) -> Self {
        let mut properties = HashMap::new();
        properties.insert("street".to_string(), address.street);
        properties.insert("city".to_string(), address.city);
        properties.insert("zip".to_string(), address.zip);
        properties
    }
}

impl From<AppUser> for user::IdentifyUser {
    fn from(app_user: AppUser) -> Self {
        Self {
            profile_id: app_user.id,
            email: app_user.email,
            first_name: app_user.first_name,
            last_name: app_user.last_name,
            properties: app_user.address.into(),
        }
    }
}

// Usage
let user = AppUser { /* ... */ };
let response = tracker.identify(user.into()).await?;
```

### Incrementing Properties

To increment a numeric property on a user profile:

```rust
let response = tracker
    .increment_property(profile_id, "visits", 1)
    .await?;
```

### Decrementing Properties

To decrement a numeric property on a user profile:

```rust
let response = tracker
    .decrement_property(profile_id, "credits", 1)
    .await?;
```

### Filtering Events

Filters are used to prevent sending events to OpenPanel in certain cases. You can filter events by passing a `filter` function to the `track` method:

```rust
use std::collections::HashMap;

let filter = |properties: HashMap<String, String>| {
    // Return true to send the event, false to skip it
    properties.contains_key("required_key")
};

let mut properties = HashMap::new();
properties.insert("name".to_string(), "rust".to_string());

let response = tracker
    .track("test_event".to_string(), Some(properties), Some(&filter))
    .await;

// If filter returns false, the event won't be sent and an Err is returned
match response {
    Ok(_) => println!("Event sent successfully"),
    Err(_) => println!("Event was filtered out"),
}
```

## Advanced Usage

### Error Handling

The SDK uses Rust's `Result` type for error handling. Always handle errors appropriately:

```rust
match tracker.track("event".to_string(), Some(properties), None).await {
    Ok(response) => {
        if response.status() == 200 {
            println!("Event tracked successfully");
        }
    }
    Err(e) => {
        eprintln!("Failed to track event: {}", e);
    }
}
```

### Async Runtime

The SDK uses async/await. Make sure you're running within an async runtime (e.g., Tokio):

```rust
#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let tracker = Tracker::try_new_from_env()?.with_default_headers()?;
    // ... use tracker
    Ok(())
}
```
