Struct style::rule_tree::StrongRuleNode

pub struct StrongRuleNode { /* fields omitted */ }

A strong reference to a rule node.

Methods

impl StrongRuleNode

pub fn ptr(&self) -> *mut RuleNode

Raw pointer to the RuleNode

pub fn style_source(&self) -> &StyleSource

Get the style source corresponding to this rule node. May return None if it's the root node, which means that the node hasn't matched any rules.

pub fn cascade_level(&self) -> CascadeLevel

The cascade level for this node

pub fn importance(&self) -> Importance

Get the importance that this rule node represents.

Important traits for SelfAndAncestors<'a>

impl<'a> Iterator for SelfAndAncestors<'a> type Item = &'a StrongRuleNode;

pub fn self_and_ancestors(&self) -> SelfAndAncestors

Get an iterator for this rule node and its ancestors.

pub unsafe fn has_children_for_testing(&self) -> bool

Returns whether this node has any child, only intended for testing purposes, and called on a single-threaded fashion only.

pub fn has_animation_or_transition_rules(&self) -> bool

Returns true if there is either animation or transition level rule.

pub fn get_properties_overriding_animations(
    &self,
    guards: &StylesheetGuards
) -> (LonghandIdSet, bool)

Get a set of properties whose CascadeLevel are higher than Animations but not equal to Transitions.

If there are any custom properties, we set the boolean value of the returned tuple to true.

pub fn get_smil_animation_rule(
    &self
) -> Option<&Arc<Locked<PropertyDeclarationBlock>>>

Returns SMIL override declaration block if exists.

Trait Implementations

impl Debug for StrongRuleNode

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Eq for StrongRuleNode

impl Hash for StrongRuleNode

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher,

impl PartialEq for StrongRuleNode

fn eq(&self, __arg_0: &StrongRuleNode) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &StrongRuleNode) -> bool

This method tests for !=.

impl MallocSizeOf for StrongRuleNode

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

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

impl Clone for StrongRuleNode

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Drop for StrongRuleNode

fn drop(&mut self)

Executes the destructor for this type.
