# Rust

### Installation

Add the following dependency to your `Cargo.toml` file:

```toml
[dependencies]
telemetry-sh = "1.0.0"
serde_json = "1.0"
chrono = "0.4"  # For handling timestamps (used in the log data)
```

#### Usage

**Import Library**

Add the necessary imports to your Rust file:

```rust
use telemetry_sh::Telemetry;
use serde_json::json;
use chrono::Utc;
```

**Initialize Client**

Initialize the `Telemetry` client with your API key:

```rust
fn main() {
    let mut telemetry = Telemetry::new();
    telemetry.init("YOUR_API_KEY".to_string());
}
```

**Log Some Data**

Telemetry automatically creates tables when data is logged. In the following example, we log some Uber ride data to a table called `uber_rides`. Telemetry will automatically create this table and its corresponding schema with columns: `city`, `price`, and `timestamp`.

```rust
fn log_data(telemetry: &Telemetry) -> Result<(), Box<dyn std::error::Error>> {
    let data = json!({
        "city": "paris",
        "price": 42,
        "timestamp": Utc::now().to_rfc3339()
    });

    let response = telemetry.log("uber_rides", &data)?;
    println!("Log response: {:?}", response);

    Ok(())
}
```

**Query Some Data**

You can query the data using SQL through the query API:

```rust
fn query_data(telemetry: &Telemetry) -> Result<(), Box<dyn std::error::Error>> {
    let query = "
        SELECT
            city,
            AVG(price) AS average_price
        FROM
            uber_rides
        GROUP BY
            city
    ";

    let query_response = telemetry.query(query)?;
    println!("Query response: {:?}", query_response);

    Ok(())
}
```

**Example Main Function**

Here is an example of how you can integrate logging and querying data in your `main` function:

```rust
fn main() {
    let mut telemetry = Telemetry::new();
    telemetry.init("YOUR_API_KEY".to_string());  // Replace with your actual API key

    if let Err(e) = log_data(&telemetry) {
        eprintln!("Error logging data: {}", e);
    }

    if let Err(e) = query_data(&telemetry) {
        eprintln!("Error querying data: {}", e);
    }
}
```

This documentation provides an overview of how to set up and use the Rust SDK for Telemetry, with examples of logging and querying data.
