//! **Note** This portal doesn't work for sandboxed applications.
//! # Examples
//!
//! ```rust,no_run
//! use ashpd::desktop::proxy_resolver::ProxyResolverProxy;
//!
//! async fn run() -> ashpd::Result<()> {
//!     let connection = zbus::Connection::session().await?;
//!     let proxy = ProxyResolverProxy::new(&connection).await?;
//!
//!     println!("{:#?}", proxy.lookup("www.google.com").await?);
//!
//!     Ok(())
//! }
//! ```
