Struct LinkedStyleSheet 

pub struct LinkedStyleSheet { /* private fields */ }

A fully-parsed style sheet file.

A linked style sheet has a scope attached. The scope can be used in style queries, to limit the style sheets which can be matched in the queries.

Implementations

impl LinkedStyleSheet

pub fn new_empty() -> Self

Create an empty style sheet file with no scope limits.

pub fn scope(&self) -> Option<NonZeroUsize>

Get the scope of the style sheet file.

pub fn sheets(&self) -> Vec<Rc<RefCell<StyleSheet>>>

Get all style sheets.

A style sheet file can contain several StyleSheet. If the file has no @import, it has only one StyleSheet. Otherwise, other StyleSheet will be imported.

All StyleSheets are ordered based on the imported order.

pub fn parse(source: &str, scope: Option<NonZeroUsize>) -> (Self, Vec<Warning>)

Parse style sheet source to a style sheet directly.

All @imports are ignored. It is a convinient way if there is no @import in the source.

pub fn get_rule(&self, rule_index: u32) -> Option<Rc<Rule>>

Get a rule by index.

pub fn add_rule(&mut self, rule: Box<Rule>) -> u32

Append a new rule.

Generally it is used for debugging. Re-query is needed when the style sheet is updated.

pub fn replace_rule( &mut self, rule_index: u32, rule: Box<Rule>, ) -> Result<Rc<Rule>, Box<Rule>>

Replace an existing rule with a new rule.

The new rule is returned if success. Generally it is used for debugging. Re-query is needed when the style sheet is updated.

pub fn get_font_face(&self) -> Vec<Rc<FontFace>>

Get all @font-face definitions.
