}

Presents the system’s file, folder and document choosers.

Implemented by the platform backends and consumed by crate::launcher.

Required Methods

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

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

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

Presents a folder chooser. Resolves to None if cancelled.

Provided Methods

fn pick_files( &self, options: FilePickerOptions, ) -> PickerFuture<Result<Vec<ContentHandle>, FilePickerError>>

Presents a multi-file chooser. Resolves to an empty vector if cancelled.

The default presents the single-file chooser, for backends whose system chooser has no multi-selection mode.

fn save_document( &self, request: SaveDocumentRequest, ) -> PickerFuture<Result<Option<ContentSinkRef>, FilePickerError>>

Presents a save-destination chooser and opens a sink on the chosen document. Resolves to None if cancelled.

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

Presents a chooser for a folder the app may keep writing to across runs, resolving to the durable handle accepted by crate::writable_folder::open_writable_folder.

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