Struct Styles 

pub struct Styles { /* private fields */ }

Every style in a document, from both of the places they live.

Implementations

impl Styles

pub fn collect(content: Option<&Element>, styles: Option<&Element>) -> Self

Collect the styles of a document from its two parts.

Both are optional because both are optional in the format: a package may carry all its formatting in automatic styles in content.xml and no styles.xml at all.

pub fn add(&mut self, element: &Element)

Take in a style an edit has written into the document, so that it resolves from now on.

Nothing is ever taken out: a style an undo removed from the tree stays here, which keeps its name from being given to a different style while a resolution of it may still be cached.

pub fn style(&self, family: &Family, name: &str) -> Option<&Style>

A style by family and name.

pub fn gradient(&self, name: &str) -> Option<&Gradient>

A gradient by name, as a fill refers to one.

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

Where the picture of a named fill image lives inside the package.

pub fn heading_style(&self, level: u8) -> Option<&str>

The paragraph style a document gives headings of a level: the one that declares style:default-outline-level as that level, and failing that the one LibreOffice names Heading_20_{level}.

pub fn has_style(&self, family: &Family, name: &str) -> bool

Whether a style of a family and name is in the document.

pub fn list_kind(&self, name: &str) -> Option<ListKind>

Whether a list style numbers its items or marks them, by the first of its levels that says.

pub fn list_style_for(&self, kind: ListKind) -> Option<&str>

A list style of a kind the document already has, the first by name.

pub fn list_style(&self, name: &str) -> Option<&Element>

A list style by name, as the text:list-style-name of a list refers to one.

pub fn master_page(&self, name: &str) -> Option<&Element>

A master page by name.

pub fn page_layout_of(&self, master_page: &str) -> Option<&PageLayout>

The page layout a master page points at.

pub fn resolve(&self, family: &Family, name: &str) -> Rc<Properties>

The resolved properties of a style, with its whole inheritance chain and its family’s default applied.

A name that is not in the document resolves to the family’s default, which is what an application does with a dangling style reference: the paragraph is shown rather than refused.

pub fn font_family(&self, declared: &str) -> String

The family the properties of a cell’s text come from: a cell style’s style:parent-style-name chain carries the paragraph and text properties, so a cell resolves in one call.
