Struct style::data::EagerPseudoStyles
source · pub struct EagerPseudoStyles(Option<Arc<EagerPseudoArray>>);
Expand description
A lazily-allocated list of styles for eagerly-cascaded pseudo-elements.
We use an Arc so that sharing these styles via the style sharing cache does not require duplicate allocations. We leverage the copy-on-write semantics of Arc::make_mut(), which is free (i.e. does not require atomic RMU operations) in servo_arc.

Implementations§
source§impl EagerPseudoStyles
impl EagerPseudoStyles
sourcepub fn as_optional_array(&self) -> Option<&[Option<Arc<ComputedValues>>; 3]>
pub fn as_optional_array(&self) -> Option<&[Option<Arc<ComputedValues>>; 3]>
Grabs a reference to the list of styles, if they exist.
sourcepub fn as_array(&self) -> &[Option<Arc<ComputedValues>>; 3]
pub fn as_array(&self) -> &[Option<Arc<ComputedValues>>; 3]
Grabs a reference to the list of styles or a list of None if there are no styles to be had.
sourcepub fn get(&self, pseudo: &PseudoElement) -> Option<&Arc<ComputedValues>>
pub fn get(&self, pseudo: &PseudoElement) -> Option<&Arc<ComputedValues>>
Returns a reference to the style for a given eager pseudo, if it exists.
sourcepub fn set(&mut self, pseudo: &PseudoElement, value: Arc<ComputedValues>)
pub fn set(&mut self, pseudo: &PseudoElement, value: Arc<ComputedValues>)
Sets the style for the eager pseudo.
