How the curl to Rust conversion works
The output uses reqwest with tokio: each -H flag becomes an entry in a HeaderMap, -u becomes basic_auth, and -d becomes .body(...) on the request builder.
Example
curl https://api.example.com/ping -H 'X-Api-Key: abc123'
becomes an async main that builds the request with reqwest::Method::GET and prints the status and body — paste your command above to see the full code.
