Module dialogs 

File dialogs.

Structs

SaveOutcome

Result of an async save. path is Some on desktop (the written filesystem path); WASM/Android drives the save through the OS so they only report success/failure.

Enums

PickedFile

A file picked by the user: a real path (desktop) or name+bytes (WASM/Android, where the OS hands us a URI/blob, not a path).

Functions

export_path

Ask for a write path without writing. Blocking. Desktop only (used by the synchronous Save flow so the unsaved guard stays correct).

init

Register platform I/O callbacks (Android only). No-op elsewhere. Must be called once at app startup.

pick_open_file

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.

save_bytes

Non-blocking save dialog that writes data. Works on every target. on_done is called with the outcome after the OS finishes.
