Struct UiModel 

pub struct UiModel { /* private fields */ }

The menu state machine.

Pure logic: no clock, no I/O. The owning task feeds it resolved gestures and renders whatever page and notice report.

Implementations

impl UiModel

pub const fn new(items: MenuItems) -> Self

pub const fn page(&self) -> Page

pub const fn notice(&self) -> Option<UiNotice>

pub const fn items(&self) -> MenuItems

pub const fn is_home(&self) -> bool

Whether the model is showing its home page with nothing pending.

The attention lapse uses this to skip a pointless redraw.

pub fn set_notice(&mut self, notice: UiNotice)

Report a result and return to the status page.

pub fn clear_notice(&mut self)

pub fn go_home(&mut self)

Drop everything transient and return to the home page.

Called when display attention lapses, so the next press always starts from a page whose meaning the user can see rather than from a confirmation they walked away from.

pub fn apply(&mut self, input: UiInput) -> Option<UiEffect>

Apply one resolved gesture.

A destructive confirmation defaults to Cancel; Forward and Backward both toggle its two choices, and Select activates the visible one.

Trait Implementations

impl Clone for UiModel

fn clone(&self) -> UiModel

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UiModel

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for UiModel

fn eq(&self, other: &UiModel) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
