ContentTypes

Struct ContentTypes 

Source
pub struct ContentTypes {
    pub defaults: Vec<DefaultExt>,
    pub overrides: Vec<Override>,
    /* private fields */
}
Expand description

[Content_Types].xml 模型。

内部用 BTreeMap 索引 by_partname 提供 O(log n) 的“是否已 override“查询; Vec<Override> 用于序列化时保留插入顺序。

Fields§

§defaults: Vec<DefaultExt>

默认项(按扩展名)。

§overrides: Vec<Override>

覆盖项(按 partname)。

Implementations§

Source§

impl ContentTypes

Source

pub fn new_default() -> ContentTypes

构造一个带默认项的 ContentTypes(xml/rels/png/jpeg/jpg/gif/bmp/svg)。

默认项与 PowerPoint 标准输出对齐,可直接被 Office 解析。

Source

pub fn add_override(&mut self, partname: &str, content_type: &str)

添加或覆盖一个 partname。

已存在则不覆盖——首个插入的 Content-Type 生效(与 python-pptx 行为一致)。

Source

pub fn has_override(&self, partname: &str) -> bool

是否已 override。

Source

pub fn to_xml(&self) -> String

转成 XML 字符串。
