语法突出显示Egui Rust

我正在使用EGUI在Rust中编辑文本编辑器。我正在尝试实现语法突出显示，因此，我在 syntax_highlighting 。我有Syntect和Egui都安装了他们的最新版本，并拥有它们作为依赖。

let mut theme = crate::syntax_highlighting::CodeTheme::from_memory(ui.ctx());
ui.collapsing("Theme", |ui| {
    ui.group(|ui| {
        theme.ui(ui);
        theme.clone().store_in_memory(ui.ctx());
    });
});


let mut layouter = |ui: &egui::Ui, string: &str, wrap_width: f32| {
    let mut layout_job = 
        crate::syntax_highlighting::highlight(ui.ctx(), &theme, string, self.language);
    layout_job.wrap.max_width = wrap_width;
    ui.fonts().layout_job(layout_job)
};

特别是，正是这些行引起的错误是在板条箱根中找不到 stytax_highlighting 。如果有用，这是我的所有代码： https://pastebin.com/mhdhlhsr

我想对我的egui应用程序进行启发，但是我发现 stytax_highlighting 在板条箱根中找不到的错误，我找到的唯一示例使用了。

I'm writing a text editor in Rust using egui. I am trying to implement syntax highlighting,
so I followed the example in the demo. It works there, so I thought it might be useful. But I am getting an error that syntax_highlighting is not found in the crate root. I have syntect and egui both installed at their latest versions and have them
as dependencies.

let mut theme = crate::syntax_highlighting::CodeTheme::from_memory(ui.ctx());
ui.collapsing("Theme", |ui| {
    ui.group(|ui| {
        theme.ui(ui);
        theme.clone().store_in_memory(ui.ctx());
    });
});


let mut layouter = |ui: &egui::Ui, string: &str, wrap_width: f32| {
    let mut layout_job = 
        crate::syntax_highlighting::highlight(ui.ctx(), &theme, string, self.language);
    layout_job.wrap.max_width = wrap_width;
    ui.fonts().layout_job(layout_job)
};

In particular, it is these lines that raise the error that syntax_highlighting is not found in the crate root. In case it's useful, here is all my code:

I want to implement syntax highlighting to my egui application, but I get the error that syntax_highlighting is not found in the crate root, which the only example I found used.
