Struct PageRule 

pub struct PageRule {
    pub selectors: PageSelectors,
    pub rules: Arc<Locked<CssRules>>,
    pub block: Arc<Locked<PropertyDeclarationBlock>>,
    pub source_location: SourceLocation,
}

A @page rule.

This implements only a limited subset of the CSS 2.2 syntax.

Fields

selectors: PageSelectors

Selectors of the page-rule

rules: Arc<Locked<CssRules>>

Nested rules.

block: Arc<Locked<PropertyDeclarationBlock>>

The declaration block this page rule contains.

source_location: SourceLocation

The source position this rule was found at.

Implementations

impl PageRule

pub fn match_specificity(&self, flags: PagePseudoClassFlags) -> Option<u32>

Computes the specificity of this page rule when matched with flags.

Computing this value has linear-complexity with the size of the selectors, so the caller should usually call this once and cache the result.

Returns None if the flags do not match this page rule.

The return type is ordered by page-rule specificity.
