## Running examples
Copy the sample config file
```bash
cp examples/config.sample.toml examples/config.toml
```

Edit values in examples/config.toml with your iot hub host, device and primary key

## Usage

```rust
#[macro_use]
extern crate log;

use azure_iot_sdk::{client::IoTHubClient, message::Message};

use serde::Deserialize;

#[derive(Debug, Deserialize)]
struct DeviceConfig {
    hostname: String,
    device_id: String,
    shared_access_key: String,
}

impl DeviceConfig {
    fn from_env() -> Result<Self, config::ConfigError> {
        let mut cfg = config::Config::default();
        cfg.merge(config::File::with_name("examples/config"))?;
        cfg.try_into()
    }
}

#[tokio::main]
async fn main() {
    env_logger::from_env(env_logger::Env::default().default_filter_or("info")).init();

    let config = DeviceConfig::from_env().unwrap();

    let mut client =
        IoTHubClient::with_device_key(config.hostname, config.device_id, config.shared_access_key)
            .await;

    info!("Initialized client");

    client
        .on_message(|msg| {
            println!("Received message {:?}", msg);
        })
        .await;

    let msg = Message::new(b"Hello, world!".to_vec());

    client.send_message(msg).await;

    std::thread::park();
}
```
