pub fn pick_open_file(
title: &'static str,
extensions: &'static [&'static str],
on_done: Box<dyn FnOnce(Option<PickedFile>) + Send + 'static>,
)Expand description
Non-blocking single-file open dialog. Works on every target:
desktop spawns a thread running the native blocking dialog. Android
spawns a thread driving the Activity picker. WASM runs the browser
picker on the main thread. on_done(None) fires on cancel/error.
