Implementations

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>; 18]

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_unknown_webkit_pseudo_element(&self) -> bool

Whether this is an unknown ::-webkit- pseudo-element.

pub fn is_marker(&self) -> bool

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

pub fn is_selection(&self) -> bool

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

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_color_swatch(&self) -> bool

Whether this pseudo-element is representing the color swatch inside an <input> element.

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_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.

See the documentation for PseudoElementCascadeType for how we choose which cascade type to use.

Note: Keep eager pseudos in sync with EAGER_PSEUDO_COUNT and EMPTY_PSEUDO_ARRAY in style/data.rs

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.

pub fn is_highlight(&self) -> bool

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

pub fn is_target_text(&self) -> bool

Whether this pseudo-element is the ::target-text pseudo.

pub fn is_lazy_painted_highlight_pseudo(&self) -> bool

Whether this is a highlight pseudo-element that is styled lazily during painting rather than during the restyle traversal. These pseudos need explicit repaint triggering when their styles change.

Trait Implementations

impl Clone for PseudoElement

fn clone(&self) -> PseudoElement

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PseudoElement

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PseudoElement

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for PseudoElement

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl MallocSizeOf for PseudoElement

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize
