Struct StyleSheet 

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

A parsed stylesheet containing an ordered list of rules.

Use StyleSheet::parse to parse a CSS-like string, then StyleSheet::resolve to compute the effective style for a component.

Fields

rules: Vec<StyleRule>

Rules in source order (higher-index rules override earlier ones for the same specificity).

Implementations

impl StyleSheet

pub fn rules(&self) -> &[StyleRule]

Returns all parsed rules.

pub fn parse(input: &str) -> Result<Self, String>

Parses a stylesheet string into a StyleSheet.

pub fn resolve( &self, type_name: &str, id: Option<&str>, class: Option<&str>, state: &WidgetState, ) -> Style

Resolves the effective style for a component by matching its type name, optional id, optional class, and pseudo-class state against all rules.

Specificity order: type < class < id. Pseudo-class rules have higher specificity than non-pseudo-class rules. Later rules override earlier ones at the same specificity.

Trait Implementations

fn clone(&self) -> StyleSheet

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StyleSheet

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for StyleSheet

fn default() -> StyleSheet

Returns the “default value” for a type.
