Struct FileDialogService 

pub struct FileDialogService { /* private fields */ }

Cloneable, window-associated application service for native file dialogs. Requests contain no native parent handle; the desktop host resolves the WindowId to the real parent only when it starts the native dialog.

Implementations

impl FileDialogService

pub const fn window_id(&self) -> WindowId

pub fn capabilities(&self) -> FileDialogCapabilities

pub async fn open_file( &self, options: FileDialogOptions, ) -> Result<Option<DocumentDescriptor>, FileDialogError>

Opens one native file picker and resolves to None when the user cancels it. Backend failures and lifecycle invalidation remain errors.

pub async fn open_files( &self, options: FileDialogOptions, ) -> Result<Option<Vec<DocumentDescriptor>>, FileDialogError>

Opens a native multi-file picker, preserving the backend’s selection order exactly. User cancellation resolves to None.

pub async fn save_file( &self, options: FileDialogOptions, ) -> Result<Option<DocumentDescriptor>, FileDialogError>

Opens a native save picker. Incular returns the selected destination path only; it never creates, truncates, or writes the file.

pub async fn select_folder( &self, options: FileDialogOptions, ) -> Result<Option<PathBuf>, FileDialogError>

Opens a native folder picker and resolves to None on user cancel.

pub fn request_open_file( &self, options: FileDialogOptions, ) -> Result<FileDialogRequest<Option<DocumentDescriptor>>, FileDialogError>

Creates an explicit request handle for callers that need request identity, manual polling, or cancellation-by-drop before awaiting.

pub fn request_open_files( &self, options: FileDialogOptions, ) -> Result<FileDialogRequest<Option<Vec<DocumentDescriptor>>>, FileDialogError>

Explicit-handle form of Self::open_files.

pub fn request_save_file( &self, options: FileDialogOptions, ) -> Result<FileDialogRequest<Option<DocumentDescriptor>>, FileDialogError>

Explicit-handle form of Self::save_file.

pub fn request_select_folder( &self, options: FileDialogOptions, ) -> Result<FileDialogRequest<Option<PathBuf>>, FileDialogError>

Explicit-handle form of Self::select_folder.
