SlideLayouts

Struct SlideLayouts 

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

全部版式的集合。

crate::presentation::Presentation 中由 slide_layouts 字段持有。 至少包含 1 个默认版式(由 crate::presentation::Presentation::new 自动创建)。

Implementations§

Source§

impl SlideLayouts

Source

pub fn new() -> Self

新建一个空集合。

Source

pub fn len(&self) -> usize

数量。

Source

pub fn is_empty(&self) -> bool

是否为空。

Source

pub fn iter(&self) -> Iter<'_, SlideLayoutRef>

遍历所有版式引用。

Source

pub fn get(&self, idx: usize) -> Option<&SlideLayoutRef>

按索引取不可变引用。

Source

pub fn get_mut(&mut self, idx: usize) -> Option<&mut SlideLayoutRef>

按索引取可变引用。

Source

pub fn at(&self, idx: usize) -> Option<SlideLayout>

取一个版式(克隆为不可变轻量句柄 SlideLayout)。

idx 越界返回 None。该 API 是 python-pptx slide_layouts[i] 的等价物。

Source

pub fn push(&mut self, layout: SlideLayoutRef)

追加一个版式(内存模型;presentation::to_opc_package 会一并写出)。

partname 必须以 /ppt/slideLayouts/slideLayout<N>.xml 形式。

Source

pub fn remove(&mut self, idx: usize) -> Option<SlideLayoutRef>

按索引移除一个版式(TODO-008)。

对标 python-pptx SlideLayouts.remove(layout)

§注意

移除版式不会自动更新引用该版式的 slide。调用方应确保没有 slide 仍在引用被移除的版式(可通过 crate::presentation::Presentation::slides_using_layout 检查)。

§返回
  • Some(SlideLayoutRef):被移除的版式;
  • None:索引越界。
Source

pub fn index_of(&self, rid: &str) -> Option<usize>

按关系 id 查找版式索引(TODO-008)。

对标 python-pptx SlideLayouts.index(layout)。 返回第一个 rid 匹配的索引;未找到返回 None

Source

pub fn get_by_name(&self, name: &str) -> Option<&SlideLayoutRef>

按名称查找版式(TODO-008)。

对标 python-pptx SlideLayouts.get_by_name(name)。 返回第一个 name 匹配的版式引用;未找到返回 None

Source

pub fn get_by_name_mut(&mut self, name: &str) -> Option<&mut SlideLayoutRef>

按名称查找版式(可变引用,TODO-008)。
