Struct CompiledStyleSheet 

pub struct CompiledStyleSheet {
    pub generation: u64,
    /* private fields */
}

A compiled stylesheet: rules indexed into buckets keyed by their primary selector part so that widget→style resolution is ~O(1) for common cases.

Rules are stored by-index in the rules vec; each bucket holds a sorted list of rule indices. Dedup is applied during lookup so a rule whose selector list covers multiple buckets is only counted once.

Construct via CompiledStyleSheet::compile.

Fields

generation: u64

Generation counter — incremented when compiled from a new stylesheet.

Implementations

impl CompiledStyleSheet

pub fn compile(sheet: &StyleSheet, generation: u64) -> Self

Compile a parsed StyleSheet into a CompiledStyleSheet.

generation is stored on the struct and used by StyleCache to detect when a compiled stylesheet has changed.

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

Compute the final ComputedStyle for a widget.

The result is semantically identical to StyleSheet::compute_style:

1. Candidate rules are collected from the relevant buckets (type, each class, id, and universal).
2. Rule indices are deduplicated.
3. For each unique rule, the first matching selector’s specificity is used (mirroring the break in StyleSheet::matching_rules).
4. Rules are sorted by (specificity, source_order) ascending and applied in that order (last-writer-wins per property).
