DiffView

虚拟化的分栏或统一文件差异视图，行同步且面板可独立横向滚动。

默认不包含任何语言语法。Rust 可注册静态链接的语法；Go 和 TypeScript 可通过 LoadLanguagePack / loadLanguagePack 加载单个跨平台包，其中包含所选 Tree-sitter Wasm 语法与查询。

组件默认不带视觉样式：文本和行号继承颜色，不添加背景、边框、圆角、内边距或语法／差异配色。外观由应用显式提供样式与颜色。

#导入

启用 QuickGUI 可选的 editor crate feature，并导入差异模型与显示类型。

use quickgui::{DiffLayout, DiffView, DiffViewStyle, IntoElement, SyntaxLanguage};

#用法

let diff = DiffView::from_texts(
    "before.rs",
    "pub const ANSWER: u8 = 41;\n",
    "after.rs",
    "pub const ANSWER: u8 = 42;\n",
)
.with_style(
    DiffViewStyle::default()
        .layout(DiffLayout::Split)
        .language(Some(SyntaxLanguage::Rust)),
);

diff.element("source-diff")

#语法高亮

DiffView 使用与 Editor 相同的内置 Tree-sitter 语法。文档、语言或语法调色板变化时，它会分别解析每个可见文件的新旧行序列，并把捕获片段分配给逻辑行。每个 RenderSide 仅在挂载时延迟构建并缓存 StyledText，再按互不重叠的字节边界合并行内新增/删除强调。滚动不会调用解析器。
