Methods

impl PseudoElement

pub fn eager_index(&self) -> usize

Gets the canonical index of this eagerly-cascaded pseudo-element.

pub fn index(&self) -> usize

An index for this pseudo-element to be indexed in an enumerated array.

pub fn pseudo_none_array<T>() -> [Option<T>; 15]

An array of None, one per pseudo-element.

pub fn from_eager_index(i: usize) -> Self

Creates a pseudo-element from an eager index.

pub fn is_before_or_after(&self) -> bool

Whether the current pseudo element is ::before or ::after.

pub fn is_before(&self) -> bool

Whether this pseudo-element is the ::before pseudo.

pub fn is_after(&self) -> bool

Whether this pseudo-element is the ::after pseudo.

pub fn is_first_letter(&self) -> bool

Whether the current pseudo element is :first-letter

pub fn is_first_line(&self) -> bool

Whether the current pseudo element is :first-line

pub fn is_eager(&self) -> bool

Whether this pseudo-element is eagerly-cascaded.

pub fn is_lazy(&self) -> bool

Whether this pseudo-element is lazily-cascaded.

pub fn is_anon_box(&self) -> bool

Whether this pseudo-element is for an anonymous box.

pub fn skip_item_based_display_fixup(&self) -> bool

Whether this pseudo-element skips flex/grid container display-based fixup.

pub fn is_precomputed(&self) -> bool

Whether this pseudo-element is precomputed.

pub fn cascade_type(&self) -> PseudoElementCascadeType

Returns which kind of cascade type has this pseudo.

For more info on cascade types, see docs/components/style.md

Note: Keep this in sync with EAGER_PSEUDO_COUNT.

pub fn canonical(&self) -> PseudoElement

Covert non-canonical pseudo-element to canonical one, and keep a canonical one as it is.

pub fn pseudo_info(&self)

Stub, only Gecko needs this

pub fn property_restriction(&self) -> Option<PropertyFlags>

Property flag that properties must have to apply to this pseudo-element.

pub fn should_exist(&self, style: &ComputedValues) -> bool

Whether this pseudo-element should actually exist if it has the given styles.

Trait Implementations

impl Clone for PseudoElement

fn clone(&self) -> PseudoElement

Returns a copy of the value.
