Struct PseudoElementChain

pub struct PseudoElementChain {
    pub primary: Option<PseudoElement>,
    pub secondary: Option<PseudoElement>,
}

A chain of pseudo-elements up to two levels deep. This is used to represent cases where a pseudo-element has its own child pseudo element (for instance .div::after::marker). If both Self::primary and Self::secondary are None, then this chain represents the element itself. Not all combinations of pseudo-elements are possible and we may not be able to calculate a style for all PseudoElementChains.

Fields

primary: Option<PseudoElement>

secondary: Option<PseudoElement>

Implementations

impl PseudoElementChain

pub fn unnested(pseudo_element: PseudoElement) -> Self

pub fn innermost(&self) -> Option<PseudoElement>

pub fn with_pseudo(&self, pseudo_element: PseudoElement) -> Self

Return a possibly nested PseudoElementChain. Currently only ::before and ::after only support nesting. If the primary PseudoElement on the chain is not ::before or ::after a single element chain is returned for the given PseudoElement.

pub fn is_empty(&self) -> bool

Trait Implementations

impl Clone for PseudoElementChain

fn clone(&self) -> PseudoElementChain

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PseudoElementChain

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

Formats the value using the given formatter.

impl Default for PseudoElementChain

fn default() -> PseudoElementChain

Returns the “default value” for a type.

impl Hash for PseudoElementChain

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 PseudoElementChain

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 PseudoElementChain

fn eq(&self, other: &PseudoElementChain) -> 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.
