Struct App 

pub struct App { /* private fields */ }

The whole TUI state: the calculator service plus view-only fields.

Implementations

impl App

pub fn new(service: CalcService, config: &Config, ui: &UiState) -> Self

Builds the app from a configured service, the loaded config and the restored UI state.

pub fn persisted_state(&self) -> PersistedState

Snapshots the session for persistence: settings, UI, variables, history.

pub fn service(&self) -> &CalcService

The calculator service, for the integration tests.

Trait Implementations

impl Screen for App

type Error = Error

The host’s error type; only needs to absorb I/O errors.

fn render(&self, frame: &mut Frame<'_>)

Draws the screen into frame.

fn handle_key(&mut self, key: KeyEvent, tui: &mut Tui) -> Result<Flow>

Handles a key press, returning whether to keep running or quit.

fn handle_paste( &mut self, text: String, tui: &mut Tui, ) -> Result<Flow, Self::Error>

Handles a bracketed paste (newlines already normalized to \n) by inserting text into the focused field. The default ignores it, so a screen without a text field need not implement this.

fn tick(&mut self)

Called on each idle tick (no input within TICK); use it to advance animations. Default: do nothing.
