### Metrics reporter for https://github.com/metrics-rs/metrics that writes to DataDog.

## Usage

### Writing to stdout

```rust
#[tokio::main]
async fn main() {
    let exporter = DataDogBuilder::default()
        .tags(vec![
            "tag1".to_string(),
            "val1".to_string()
        ])
        .build()
        .install()
        .unwrap();
    exporter.flush.await()?;
}
```

### Writing to API

```rust
#[tokio::main]
async fn main() {
    let exporter = DataDogBuilder::default()
        .write_to_stdout(false)
        .write_to_api(true, Some("DD_API_KEY".to_string()))
        .tags(vec![
            "tag1".to_string(),
            "val1".to_string()
        ])
        .build()
        .install()
        .unwrap();
    exporter.flush.await()?;
}
```

### Writing on a schedule

```rust
#[tokio::main]
async fn main() {
    let exporter = DataDogBuilder::default()
        .write_to_stdout(false)
        .write_to_api(true, Some("DD_API_KEY".to_string()))
        .tags(vec![
            "tag1".to_string(),
            "val1".to_string()
        ])
        .build()
        .install()
        .unwrap();
    let (_exporter, _scheduled) = exporter.schedule(Duration::from_secs(10));
}
```
