Enum SelectorWrapper

pub enum SelectorWrapper<'a> {
    Borrowed(&'a DomRoot<Element>),
    Owned(DomRoot<Element>),
}

A type that wraps a DomRoot value so we can implement the SelectorsElement trait without violating the orphan rule. Since the trait assumes that the return type and self type of various methods is the same type that it is implemented against, we need to be able to represent multiple ownership styles.

Variants

Borrowed(&'a DomRoot<Element>)

Owned(DomRoot<Element>)

Implementations

impl SelectorWrapper<'_>

fn into_owned(self) -> DomRoot<Element>

Methods from Deref<Target = DomRoot<Element>>

pub fn as_ptr(&self) -> *const T

pub fn as_traced(&self) -> Dom<T>

Create a traced version of this rooted object.

Safety

This should never be used to create on-stack values. Instead these values should always end up as members of other DOM objects.

Trait Implementations

fn is_link(&self) -> bool

Whether this element is a link.

fn has_id(&self, id: &AtomIdent, case_sensitivity: CaseSensitivity) -> bool

fn is_part(&self, _name: &AtomIdent) -> bool

fn imported_part(&self, _: &AtomIdent) -> Option<AtomIdent>

fn is_html_slot_element(&self) -> bool

Returns whether the element is an HTML element.

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.

fn has_custom_state(&self, _name: &AtomIdent) -> bool

fn pseudo_element_originating_element(&self) -> Option<Self>

The parent of a given pseudo-element, after matching a pseudo-element selector.

impl<'a> PartialEq for SelectorWrapper<'a>

fn eq(&self, other: &SelectorWrapper<'a>) -> 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.
