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>; 19]

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 the ::-moz-color-swatch pseudo.

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.

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

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl PartialEq for PseudoElement

fn eq(&self, other: &PseudoElement) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PseudoElement for PseudoElement

type Impl = SelectorImpl

The SelectorImpl this pseudo-element is used for.

fn accepts_state_pseudo_classes(&self) -> bool
