dialogs.rs

1//! Native dialogs backed by rfd. Registered by [`crate::App::with_dialogs`].
2//!
3//! On macOS, `NSOpenPanel` / `NSSavePanel` / `NSAlert` must run on the
4//! main (UI) thread. Because fude's IPC handler runs on a background
5//! thread, every dialog call is dispatched via [`crate::MainDispatcher`]
6//! and blocks the caller until the user dismisses the dialog.
