Struct RootMenu 

pub struct RootMenu { /* private fields */ }

Top-level configuration menu (the first real Dialog impl).

Owns a fixed list of seven entries, an integer cursor, a snapshot of the current SerialConfig / LineEndingConfig (passed on to sub-dialogs), and a rendering style. Emits DialogOutcome::Push for every non-exit selection and DialogOutcome::Close for Esc / “Exit menu”.

Implementations

impl RootMenu

pub const fn new( initial_config: SerialConfig, initial_line_endings: LineEndingConfig, initial_modem: ModemLineSnapshot, initial_modal_style: ModalStyle, cli_overrides: Vec<&'static str>, ) -> Self

Construct a root menu with the cursor on the first item and snapshotting initial_config, initial_line_endings, initial_modem, initial_modal_style, and cli_overrides for forwarding to sub-dialogs (SerialPortSetupDialog, LineEndingsDialog, ModemControlDialog, and ScreenOptionsDialog).

cli_overrides carries short flag labels (-b, -d, …) for every CLI argument that overrode a profile value at startup. Pass Vec::new() when no flags override anything; the SerialPortSetupDialog skips its hint line in that case.

pub const fn selected(&self) -> usize

Current cursor position (0-based).

pub const fn items(&self) -> &'static [&'static str]

Items in display order.
