last_export_summary: Option<ExportSummary>

Snapshot of the most-recent finished export — drives the post-render summary panel. Cleared when the user starts a new export.

presets: Vec<ExportPreset>

User-saved export setting bundles. Loaded from presets.json at startup, written back on every change.

active_preset: Option<String>

Name of the preset that was last applied, if any. Shown in the Export Settings panel header so the user can see why the current settings look the way they do.

preset_picker: PresetPickerState

State of the preset-picker overlay.

preset_naming: Option<PresetNamingState>

True while the user is typing a name for a new preset. Captures the live text and the cursor position. Esc cancels, Enter saves.

spinner_frame: u8

progress_anim_offset: u8

fps_counter: FPSCounter

shockwave_ticks_remaining: u8

grade_strip_active: bool

grade_morph: Option<(usize, u8)>

Implementations

impl App

pub fn new() -> Self

pub fn load_file(&mut self, path: String)

pub fn load_files_batch(&mut self, paths: &[String]) -> (usize, usize)

Add multiple files to the media pool (used by drag-drop). Returns (imported_count, failed_count).

pub fn start_async_import(&mut self, paths: Vec<String>)

Start async import of dropped files on a background thread. Returns immediately; results arrive via DropImportEvent channel.

pub fn poll_drop_import(&mut self)

Poll for async drag-drop import results. Call every frame.

pub fn load_all_in_folder(&mut self, dir: &Path)

pub fn focused_file_info(&self) -> Option<&McrawFileInfo>

pub fn toggle_media_pool_selection(&mut self)

pub fn add_selected_to_queue(&mut self)

pub fn add_all_to_queue(&mut self)

pub fn remove_from_media_pool(&mut self)

pub fn toggle_queue_selection(&mut self)

pub fn remove_from_queue(&mut self)

pub fn clear_completed_queue(&mut self)

pub fn render_selected(&mut self)

pub fn render_all(&mut self)

pub fn active_profile_is_8bit(&self) -> bool

pub fn active_profile_name(&self) -> &'static str

pub fn cycle_rate_control(&mut self)

pub fn cycle_codec(&mut self, forward: bool)

pub fn cycle_profile(&mut self, forward: bool)

pub fn start_export(&mut self)

pub fn remove_selected_from_media_pool(&mut self)

pub fn set_export_folder(&mut self, folder: PathBuf)

pub fn toggle_favourite_folder(&mut self, folder: PathBuf)

pub fn save_current_as_preset(&mut self, name: String)

Snapshot the current export settings as a named preset and persist the full preset list to disk. If a preset with the same name already exists it is replaced in place.

pub fn apply_preset(&mut self, index: usize)

Apply the preset at the given index, copying every field onto the app’s live state.

pub fn delete_preset(&mut self, index: usize)

Delete the preset at the given index. If that preset was the active one, clear the active marker.

pub fn open_preset_picker(&mut self)

Open the preset picker overlay. If there are no presets, surface a hint in the status bar instead of opening an empty list.

pub fn close_preset_picker(&mut self)

pub fn begin_naming_preset(&mut self)

Enter the in-line naming mode for a new preset. The user types the name and presses Enter to save.

pub fn cancel_naming_preset(&mut self)

pub fn commit_naming_preset(&mut self)

Finalize naming: save the preset and exit the naming state.

pub fn current_matches_preset(&self, name: &str) -> bool

True if the current settings exactly match the named preset (best effort: only checked for the fields we know about).

pub fn import_selected_from_browser(&mut self)

pub fn cancel_export(&mut self)

pub fn poll_export(&mut self)

pub fn add_encode_job(&mut self, format: OutputFormat)

pub fn select_file(&mut self)

pub fn scan_mcraw_files_in_folder(&self, folder: &str) -> Vec<String>

Scan a folder for all .mcraw files and return sorted paths

pub fn navigate_browser(&mut self, direction: BrowserDirection)

pub fn navigate_favourites(&mut self, delta: i64)

Move the favourites-list cursor by delta. Clamps to bounds.

pub fn open_selected_favourite(&mut self)

Navigate into the favourite at the current cursor position.

pub fn delete_selected_favourite(&mut self)

Delete the favourite at the current cursor position.

pub fn cycle_focus(&mut self)

pub fn set_focus(&mut self, target: FocusTarget)
