Struct Rule 

pub struct Rule {
    pub selectors: Vec<SelectorBuf>,
    pub declarations: Vec<Declaration>,
    pub origin: Origin,
    pub source_order: usize,
    pub media: Option<MediaQuery>,
    pub selector: LegacySelectorShim,
}

One CSS rule (one selector_list { decl* } block).

Fields

selectors: Vec<SelectorBuf>

Compound selector list (each entry is one selector in the comma-separated list).

declarations: Vec<Declaration>

property: value pairs in source order, with !important resolved at parse time.

origin: Origin

Cascade origin. Defaults to Origin::Author; the runtime tags the built-in skin sheet as Origin::UserAgent before the combined cascade pass. The first term of the cascade sort.

source_order: usize

Source ordinal across the stylesheet (the last tiebreaker in the cascade sort).

media: Option<MediaQuery>

@media (...) enclosing query, if any.

selector: LegacySelectorShim

Back-compat shim that exposes the leftmost compound of the first selector under the old single-Selector shape - the Stylesheet::root_vars and StyleInvalidationCache paths still poke at rule.selector.classes / rule.selector.tag.
