Enum style::stylesheets::scope_rule::ImplicitScopeRoot

pub enum ImplicitScopeRoot {
    InLightTree(OpaqueElement),
    DocumentElement,
    Constructed,
    InShadowTree(OpaqueElement),
    ShadowHost(OpaqueElement),
}

Types of implicit scope root.

Variants

InLightTree(OpaqueElement)

This implicit scope root is in the light tree.

DocumentElement

This implicit scope root is the document element, regardless of which (light|shadow) tree the element being matched is. This is the case for e.g. if you specified an implicit scope within a user stylesheet.

Constructed

The implicit scope root is in a constructed stylesheet - the scope root the element under consideration’s shadow root (If one exists).

InShadowTree(OpaqueElement)

This implicit scope root is in the shadow tree.

ShadowHost(OpaqueElement)

This implicit scope root is the shadow host of the stylesheet-containing shadow tree.

Implementations

impl ImplicitScopeRoot

pub fn matches_shadow_host(&self) -> bool

Return true if this matches the shadow host.

pub fn element( &self, current_host: Option<OpaqueElement>, ) -> ImplicitScopeTarget

Return the implicit scope root element.

Trait Implementations

Performs copy-assignment from source.

impl Debug for ImplicitScopeRoot

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

Formats the value using the given formatter.

impl MallocSizeOf for ImplicitScopeRoot

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