/// Returns true if the operation has succeeded.
///
/// # Platform specific behavior
///
/// - On macOS, this function calls *activateFileViewerSelectingURLs* in *NSWorkspace*.
///   Unfortunately, the ObjectiveC function relies on the presence of NSRunLoop, as such,
///   *show_in_files* will also call *runUntilDate* in *NSRunLoop* which also means that
///   **this function will return false if called from a different thread than the main thread**.
///
/// - On iOS, this function always returns false because there is no matching functionality in UIKit.
///
/// - On Windows, this function always returns false because WinAPI doesn't have a matching
///   equivalent.
///
/// - On Linux and most other unix systems, this function attempts to call the dbus function
///   *ShowItems* in *org.freedesktop.FileManager1*. If no dbus connection could be made this
///   function returns false.
///
///   **Note: Not all file explorers are created equal under Linux, so the behavior of this
///   function depends on the file explorer.**

///
/// Returns true if the operation has succeeded.
///
/// # Platform specific behavior
///
/// - On macOS, this function calls *openURL* in *NSWorkspace*.
///
/// - On iOS, this function currently returns false.
///
/// - On Windows, this function calls *ShellExecuteW* with the "open" operation.
///
/// - On Linux and most other unix systems, this function calls the dbus function *ShowFolders* in
///   *org.freedesktop.FileManager1* when the URL is a path to a directory, otherwise the function
///   attempts to execute the *xdg-open* command line tool with the URL string as argument.
///
/// # Arguments
///
/// * `url`: the URL to open.
