Struct StyleSheet 

pub struct StyleSheet {
    pub rules: Vec<Rule>,
}

A parsed stylesheet containing zero or more rules.

Fields

rules: Vec<Rule>

The rules parsed from the CSS source, in source order.

Implementations

impl StyleSheet

pub fn parse(input: &str) -> ParseResult

Parse a CSS-subset string.

Malformed rules are skipped with ParseDiagnostics rather than causing a panic. Valid rules following a malformed one are still parsed.

pub fn matching_rules<'a>( &'a self, widget_type: &str, classes: &[&str], id: Option<&str>, ) -> Vec<(&'a Rule, Specificity)>

Find all rules that match a widget described by type, classes, and id.

Returns rules sorted ascending by (specificity, source_order) so that the caller can apply them in order and the last write wins (standard CSS cascade).

pub fn compute_style( &self, widget_type: &str, classes: &[&str], id: Option<&str>, ) -> ComputedStyle

Compute the final ComputedStyle for a widget by cascading all matching rules.

Rules are applied in ascending specificity / source-order, so the last (most specific) rule wins for each property.
