Struct style::invalidation::element::relative_selector::RelativeSelectorDependencyCollector

pub struct RelativeSelectorDependencyCollector<'a, E>where
    E: TElement,{
    dependencies: FxHashMap<E, SmallVec<[(Option<OpaqueElement>, &'a Dependency); 1]>>,
    invalidations: SmallVec<[(E, Option<OpaqueElement>, &'a Dependency); 2]>,
    top: E,
    optimization_context: Option<OptimizationContext<'a, E>>,
}

Interface for collecting relative selector dependencies.

Fields

dependencies: FxHashMap<E, SmallVec<[(Option<OpaqueElement>, &'a Dependency); 1]>>

Dependencies that need to run through the normal invalidation that may generate a relative selector invalidation.

invalidations: SmallVec<[(E, Option<OpaqueElement>, &'a Dependency); 2]>

Dependencies that created an invalidation right away.

top: E

The top element in the subtree being invalidated.

optimization_context: Option<OptimizationContext<'a, E>>

Optional context that will be used to try and skip invalidations by running selector matches.

Implementations

impl<'a, E> RelativeSelectorDependencyCollector<'a, E>where E: TElement,

fn new(top: E, optimization_context: Option<OptimizationContext<'a, E>>) -> Self

fn insert_invalidation( &mut self, element: E, dependency: &'a Dependency, host: Option<OpaqueElement> )

pub fn add_dependency( &mut self, dependency: &'a Dependency, element: E, host: Option<OpaqueElement> )

Add this dependency, if it is unique (i.e. Different outer dependency or same outer dependency but requires a different invalidation traversal).

fn get(self) -> ToInvalidate<'a, E>

Get the dependencies in a list format.

fn collect_all_dependencies_for_element( &mut self, element: E, scope: Option<OpaqueElement>, quirks_mode: QuirksMode, map: &'a RelativeSelectorInvalidationMap, operation: DomMutationOperation )
