ashpd 0.2.3

//! # Examples
//!
//! ```rust, no_run
//! use ashpd::desktop::account;
//! use ashpd::WindowIdentifier;
//!
//! async fn run() -> ashpd::Result<()> {
//!     let user_info = account::user_information(
//!         &WindowIdentifier::default(),
//!         "App would like to access user information",
//!     ).await?;
//!
//!     println!("Name: {}", user_info.name());
//!     println!("ID: {}", user_info.id());
//!
//!     Ok(())
//! }
//! ```
//!
//! Or by using the Proxy directly
//!
//! ```rust,no_run
//! use ashpd::desktop::account::AccountProxy;
//! use ashpd::WindowIdentifier;
//!
//! async fn run() -> ashpd::Result<()> {
//!     let connection = zbus::Connection::session().await?;
//!
//!     let proxy = AccountProxy::new(&connection).await?;
//!     let user_info = proxy
//!         .user_information(
//!             &WindowIdentifier::default(),
//!             "App would like to access user information",
//!         )
//!         .await?;
//!
//!     println!("Name: {}", user_info.name());
//!     println!("ID: {}", user_info.id());
//!
//!     Ok(())
//! }
//! ```
