Struct ElementWrapper 

pub struct ElementWrapper<'a> { /* private fields */ }

Adapter wrapping a DOM node for selector matching.

This type implements the selectors::Element trait, allowing our arena-based DOM to be matched against CSS selectors.

Implementations

Returns whether this element matches :root, i.e. whether it is the root element of a document.

fn apply_selector_flags(&self, _flags: ElementSelectorFlags)

Sets selector flags on the elemnt itself or the parent, depending on the flags, which indicate what kind of work may need to be performed when DOM state changes.

fn add_element_unique_hashes(&self, _filter: &mut BloomFilter) -> bool

Add hashes unique to this element to the given filter, returning true if any got added.

impl PartialEq for ElementWrapper<'_>

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