pseudos: SmallVec<[PagePseudoClass; 4]>

Pseudo-classes for @page

Implementations

impl PageSelector

pub fn ident_matches(&self, other: &CustomIdent) -> bool

Checks if the ident matches a page-name’s ident.

This does not take pseudo selectors into account.

pub fn matches(&self, name: &CustomIdent, flags: PagePseudoClassFlags) -> bool

Checks that this selector matches the ident and all pseudo classes are present in the provided flags.

pub fn flags_match(&self, flags: PagePseudoClassFlags) -> bool

Checks that all pseudo classes in this selector are present in the provided flags.

Equivalent to, but may be more efficient than:

match_specificity(flags).is_some()

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

Implements specificity calculation for a page selector given a set of page pseudo-classes to match with. If this selector includes any pseudo-classes that are not in the flags, then this will return None.

To fit the specificity calculation into a 32-bit value, this limits the maximum count of :first and :blank to 32767, and the maximum count of :left and :right to 65535.
