Crate mobiler_ui 

Mobiler’s fixed UI wire ABI.

These types are the stable contract between any Mobiler app’s Rust core and the native shell. Because they never change per app, a single shell is built once and renders any Mobiler app — the shell only ever knows these types, never an app’s domain events or widgets.

• The core emits a Widget tree (the ViewModel).
• The shell sends back an Action (the Event).
• App domain events ride inside actions as opaque ActionTokens that the shell round-trips without interpreting.

Style is expressed as intent tokens (e.g. TextStyle, Tone); the shell maps each to a concrete look (font, color, dp), so dark mode and theme come for free on the native side.

Structs

Fab

A floating action button anchored over the scaffold body (the raised primary action).

Rgb

A 24-bit RGB color. Used for a theme’s brand/seed color — the one place an app supplies an arbitrary color (everything else is intent tokens).

Segment

One option in a Widget::Segmented control (mirrors Tab). selected marks the active segment; tapping sends on_select.

Sheet

A modal bottom sheet anchored over the scaffold body (a scrim behind, a panel rising from the bottom). Present (Some) ⇒ open; tapping the scrim/handle sends on_dismiss.

SwipeButton

One revealed action in a SwipeAction row (swipe to reveal, tap to fire).

Tab

A bottom-navigation tab. selected marks the active one; tapping sends on_select. icon (optional) renders above the label for an icon tab bar.

Theme

App branding as data — the visual twin of dark_mode. Set on a Widget::Scaffold (theme: None = the framework defaults, i.e. no visual change). The shell maps these to its native theming: seed → the brand/primary color (Android M3 scheme / iOS tint / web --primary), plus a global corner, spacing, and font choice.

Enums

Action

What the shell sends back to the core. Fixed across all apps.

BoxAlign

ButtonStyle

CardStyle

ChartStyle

How a Chart draws its values.

Corner

Global corner-radius scale. Medium ≈ the current (un-themed) look.

Density

Global spacing scale. Comfortable ≈ the current (un-themed) spacing.

FontFamily

A finite, cross-platform font family (maps to each platform’s nearest system font design — no bundled font files). System ≈ the current look.

Icon

A finite icon set (maps to Material icons / SF Symbols / web glyphs per shell). Grouped: editing, navigation/chrome, content, and domain icons.

ImageRatio

ImageShape

InputValue

A value produced by an input widget at runtime.

ProjectColor

Project-identity colors (distinct from semantic Tone). Concrete RGB decided in the render layer.

Spacing

TextStyle

Tone

Semantic status color (distinct from brand/identity color).

Widget

The app-agnostic widget tree the shell renders. Fixed across all apps.

Type Aliases

ActionToken

An opaque, serialized app event (e.g. JSON of the app’s domain action).
