组件化设计模式

无状态组件

// 使用 RenderOnce trait
impl RenderOnce for StatelessComponent {
    fn render(self, cx: &mut WindowContext) -> impl IntoElement {
        div()
            .bg(cx.theme().colors.surface)
            .child("Content")
    }
}

有状态组件

// 使用 Render trait
struct MyComponent {
    count: usize,
    text: SharedString,
}

impl Render for MyComponent {
    fn render(&mut self, cx: &mut ViewContext<Self>) -> impl IntoElement {
        div()
            .child(
                h1()
                    .text_2xl()
                    .font_bold()
                    .child("My Component")
            )
            .child(
                div()
                    .mt_4()
                    .child(format!("Count: {}", self.count))
            )
            .child(
                button("Increment", move |_, cx| {
                    self.count += 1;
                    cx.notify();
                })
            )
    }
}

样式系统

样式链式调用

div()
    // 尺寸
    .w_full()
    .h_10()
    .min_w_0()
    .max_w_80percent()

    // 间距
    .p_4()
    .px_4()
    .py_2()
    .m_auto()
    .mt_4()

    // 布局
    .flex()
    .flex_col()
    .items_center()
    .justify_center()
    .gap_4()
    .grid()
    .grid_cols_3()

    // 颜色
    .bg(cx.theme().colors.background)
    .text_color(cx.theme().colors.foreground)
    .border_color(cx.theme().colors.border)

    // 边框
    .border_1()
    .border_2()
    .border_t_1()
    .rounded_md()
    .rounded_lg()
    .rounded_full()

    // 阴影
    .shadow_sm()
    .shadow_md()
    .shadow_lg()

    // 交互
    .cursor_pointer()
    .transition()
    .hover(|s| s.bg(cx.theme().colors.hover))
    .active(|s| s.bg(cx.theme().colors.active))
    .focus(|s| s.border_color(cx.theme().colors.primary))

    // 动画
    .animate()
    .duration_150()
    .ease_in_out()
