Trait FileDialogs 

pub trait FileDialogs:
    Send
    + Sync
    + 'static {
    // Required methods
    fn open_file(&self, request: FileDialog) -> Option<PathBuf>;
    fn open_files(&self, request: FileDialog) -> Vec<PathBuf>;
    fn save_file(&self, request: FileDialog) -> Option<PathBuf>;
    fn pick_folder(&self, request: FileDialog) -> Option<PathBuf>;
}

The OS file-chooser, as the vocabulary crate sees it.

Every method BLOCKS until the user answers, which is why the whole trait is Send + Sync: the caller runs it on a worker thread and takes the answer back on the UI thread. Nothing here touches the event loop, so a backend is free to be a portal call, a native panel, or a stub in a test.

Required Methods

fn open_file(&self, request: FileDialog) -> Option<PathBuf>

fn open_files(&self, request: FileDialog) -> Vec<PathBuf>

fn save_file(&self, request: FileDialog) -> Option<PathBuf>

fn pick_folder(&self, request: FileDialog) -> Option<PathBuf>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
