Expand description

枚举所有支持的注释类型。

这是对外最常用的统一入口：不管实际是文本、高亮、线条还是图章，最后都能先装进 Annotation 里。统一收口的注释总类型。

当前项目支持的各种注释，最后都会被包进这个枚举里。

这样外层逻辑就不用到处分别处理十几种结构体，而是可以先拿一个统一的 Annotation，再根据类型做分发。

Implementations§

Source §

impl Annotation

Source

pub fn annotation_type(&self) -> &'static str

返回注释的类型名称。

Source

pub fn base(&self) -> &AnnotationBase

返回基础属性引用。

当外层逻辑只关心“公共字段”时，不需要先判断具体是哪种注释，直接通过这个方法拿 AnnotationBase 就行。

Source

pub fn page(&self) -> usize

返回页码。

Source

pub fn rect(&self) -> Option<&Rect>

返回边界矩形。
