Trait UseTheme 

pub trait UseTheme: Sealed {
    // Required methods
    fn use_palette(&self) -> Palette;
    fn use_component_theme<T: ComponentTheme>(&self) -> T;
}

读取主题的 Hook 扩展(函数组件开箱即用;手写 Component 需先 hooks.with_context_stack(updater.component_context_stack()),或改用 ComponentUpdater::use_palette / ComponentUpdater::use_component_theme)。

Required Methods

fn use_palette(&self) -> Palette

读取当前 Palette(owned 值);无 PaletteProvider 时回退 Palette::default。

fn use_component_theme<T: ComponentTheme>(&self) -> T

按解析链读取某组件主题:显式 override context → from_palette → default。

In older versions of Rust, dyn compatibility was called "object safety".
