Struct DocMeta 

pub struct DocMeta {
    pub file_type: String,
    pub page_count: usize,
    pub text_length: usize,
    pub image_count: usize,
    pub image_text_length: usize,
    pub extra: BTreeMap<String, String>,
}

Fields

file_type: String

page_count: usize

text_length: usize

image_count: usize

image_text_length: usize

extra: BTreeMap<String, String>

插件级附加信息：书籍元数据（书名/作者/语言/封面路径）、处理链告警等。 空时不进 JSON。与 Python 参考实现的 meta.extra 对齐。
