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

/// It is not a portal in the strict sense, since it does not involve user

/// via a library API such as the GLib [`gio::ProxyResolver`](https://gtk-rs.org/gtk-rs-core/stable/latest/docs/gio/struct.ProxyResolver.html) interface.
///
/// Wrapper of the DBus interface: [`org.freedesktop.portal.ProxyResolver`](https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.portal.ProxyResolver.html).
