//! A crate for opening URIs, e.g., URLs, `tel:`, `mailto:`, `file://`, etc.
//!
//! ```
//! # use robius_open::Uri;
//! Uri::new("tel:+61 123 456 789")
//!     .open()
//!     .expect("failed to open telephone URI");
//! ```
//!
//! Supports:
//! - macOS (`NSWorkspace`)
//! - Android (`android/content/Intent`)
//! - Linux (`xdg-open`)
//! - Windows (`start`)
//! - iOS (`UIApplication`)
//!
//! # Android
//! To use the library on Android, you must add the following to the app
//! manifest:
//! ```xml
//! <uses-permission android:name="android.permission.QUERY_ALL_PACKAGES"
//!     tools:ignore="QueryAllPackagesPermission" />
//!
//! <queries>
//!     <intent>
//!         <action android:name="android.intent.action.MAIN" />
//!     </intent>
//! </queries>
//! ```
//! or alternatively, disable the `android-result` feature. However, disabling
//! this feature will make [`Uri::open`] always return `Ok`, regardless of
//! whether the URI was successfully opened.
#![allow(clippy::result_unit_err)]
