Module status_mapping 

Status mapping code generation for widget state styling

This module generates Rust code that maps Iced widget-specific status enums to Dampen’s unified WidgetState enum. This enables state-aware styling in codegen mode (matching the behavior of interpreted mode).

Architecture

The generated code mirrors the runtime status mapping logic from dampen-iced::style_mapping, but produces compile-time Rust code instead of runtime function calls.

Example Generated Code

For a button with hover styling:

let style = move |_theme: &Theme, status: iced::widget::button::Status| {
    use iced::widget::button::Status;
    let widget_state = match status {
        Status::Active => None,
        Status::Hovered => Some(dampen_core::ir::WidgetState::Hover),
        Status::Pressed => Some(dampen_core::ir::WidgetState::Active),
        Status::Disabled => Some(dampen_core::ir::WidgetState::Disabled),
    };

    if let Some(state) = widget_state {
        // Apply state-specific styling
    } else {
        // Apply base styling
    }
};
button.style(style)
