	# HTTP client for Nasqueron Datasources components

	The crate ds-http-client is a HTTP client
	based on Hyper / reqwest components.

	It can be used to download a file on an HTTP server,
	or query an API with User-Agent header.

	## Usage example

	### Initialize a client

	```
	use ds_http_client::Client;

	let mut headers = HashMap::new();
	headers.insert(
	"User-Agent".to_string(),
	"foo/1.2.3".to_string(),
	);

	let client = Client::new(Some(headers));
	```

	### Download a file

	```
	let url = "http://www.example.com/example.tar.gz";
	let target_path = "/tmp/example.tar.gz";

	if let Err(error) = client().download(&url, &target_path).await {
	eprintln!("Can't download file: {:?}", error);
	}
	```
