SlideLayoutRef

Struct SlideLayoutRef 

Source
pub struct SlideLayoutRef { /* private fields */ }
Expand description

单个版式的引用。

设计上使用 Rc<RefCell<OxmlSldLayout>>直接拥有,以兼容“版式被母版 与页共享引用“的未来场景。当前实现下每个版式只被一个 SlideLayouts 拥有。

Implementations§

Source§

impl SlideLayoutRef

Source

pub fn partname(&self) -> &str

取出 part 路径(如 /ppt/slideLayouts/slideLayout1.xml)。

Source

pub fn rid(&self) -> &str

取出关系 id(如 rIdLayout1)。

Source

pub fn name(&self) -> String

取版式名(对应 OOXML 中的 <p:sldLayout name="..."/>)。

Source

pub fn set_name(&mut self, n: String)

设置版式名。

Source

pub fn layout_type(&self) -> String

取版式类型(OOXML 中的 type 属性,可选;如 blank / title / section)。

Source

pub fn set_layout_type(&mut self, t: String)

设置版式类型。

Source

pub fn shapes(&self) -> Vec<OxmlSp>

不可变 shape 列表(python-pptx slide_layout.shapes 风格)。

返回的是 OxmlSp 句柄的借用,不触发 clone;适合“只读浏览“。

Source

pub fn shapes_mut(&self) -> RefMut<'_, Vec<OxmlSp>>

可变 shape 列表。

Source

pub fn placeholders(&self) -> Vec<Placeholder>

占位符列表(python-pptx slide_layout.placeholders 风格)。

当前实现把所有带 is_placeholder=trueOxmlSp 视作占位符。 返回不可变快照,避免借用期跨越。

Source

pub fn placeholder_indices(&self) -> Vec<usize>

返回所有占位符在 shapes 中的索引列表(TODO-008)。

用于配合 shapes_mut 按索引修改占位符:

let indices = layout.placeholder_indices();
let mut shapes = layout.shapes_mut();
for i in indices {
    // 修改第 i 个 shape(它是占位符)
    shapes[i].name = format!("PH {}", i);
}
Source

pub fn placeholder_index_by_ph_idx(&self, ph_idx: u32) -> Option<usize>

ph_idx 查找占位符在 shapes 中的索引(TODO-008)。

返回第一个 ph_idx 匹配的 shapes 索引;未找到返回 None。 用于配合 shapes_mut 修改特定占位符。
