Trait FilePicker 

pub trait FilePicker {
    // Required methods
    fn pick_file(
        &self,
        options: FilePickerOptions,
    ) -> PickerFuture<Result<Option<PickedEntryRef>, FilePickerError>>;
    fn pick_folder(
        &self,
        options: FilePickerOptions,
    ) -> PickerFuture<Result<Option<PickedEntryRef>, FilePickerError>>;

    // Provided method
    fn pick_folder_streaming(
        &self,
        options: FilePickerOptions,
    ) -> PickerFuture<Result<Option<FolderStreamRef>, FilePickerError>> { ... }
}

Presents native file and folder pickers.

Required Methods

fn pick_file( &self, options: FilePickerOptions, ) -> PickerFuture<Result<Option<PickedEntryRef>, FilePickerError>>

Presents a single-file picker. Resolves to None if cancelled.

fn pick_folder( &self, options: FilePickerOptions, ) -> PickerFuture<Result<Option<PickedEntryRef>, FilePickerError>>

Presents a folder/tree picker. Resolves to None if cancelled.

Provided Methods

fn pick_folder_streaming( &self, options: FilePickerOptions, ) -> PickerFuture<Result<Option<FolderStreamRef>, FilePickerError>>

Presents a folder picker and streams the tree’s files as they are discovered (see FolderStream).

The default walks the picked folder eagerly via pick_folder and yields every file at once; backends served by a slow provider (Android’s Storage Access Framework) override this to stream during the walk. Resolves to None if cancelled.

Dyn Compatibility

This trait is dyn compatible.

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