Field

Struct Field 

Source
pub struct Field {
    pub id: String,
    pub field_type: FieldType,
    pub properties: RunProperties,
    pub text: String,
}
Expand description

字段(<a:fld>)。

对标 python-pptx 中字段对象。字段是段落中特殊的“动态文本“, 如幻灯片编号、日期时间、页脚等,由 PowerPoint 在渲染时自动填充。

§OOXML 结构

<a:fld id="{GUID}" type="slidenum">
  <a:rPr .../>
  <a:t>1</a:t>
</a:fld>

Fields§

§id: String

字段 GUID(id 属性)。PowerPoint 用此关联字段实例。

§field_type: FieldType

字段类型(type 属性)。

§properties: RunProperties

Run 属性(<a:rPr>)。

§text: String

字段文本(<a:t>)——渲染前的占位文本。

Implementations§

Source§

impl Field

Source

pub fn new(field_type: FieldType, text: impl Into<String>) -> Field

创建一个指定类型的字段。

§参数
  • field_type:字段类型;
  • text:占位文本(如幻灯片编号用 "1",日期用 "1/1/2024")。
Source

pub fn write_xml(&self, w: &mut XmlWriter)

写 XML。
