Selector matching.

Structs

CascadeData

Data resulting from performing the CSS cascade that is specific to a given origin.

CascadeDataCache 🔒

CascadeDataCacheKey 🔒

A key in the cascade data cache.

CascadeLayer 🔒

ContainerConditionId

The id of a given container condition, a sequentially-increasing identifier for a given style set.

ContainerConditionReference 🔒

ContainingRuleState 🔒

A struct containing state from ancestor rules like @layer / @import / @container / nesting / @scope.

DocumentCascadeData

All the computed information for all the stylesheets that apply to the document.

DocumentCascadeDataIter

An iterator over the cascade data of a given document.

EMPTY_UA_CASCADE_DATA 🔒

The empty UA cascade data for un-filled stylists.

ExtraStyleData

This struct holds data which users of Stylist may want to extract from stylesheets which can be done at the same time as updating.

ExtraStyleDataIterator

An iterator over the different ExtraStyleData.

GenericElementAndPseudoRules 🔒

A set of rules for element and pseudo-elements.

IMPLICIT_SCOPE 🔒

LayerId

The id of a given layer, a sequentially-increasing identifier.

LayerOrderedMap

A map that is sorted in layer order.

LayerOrderedVec

A vector that is sorted in layer order.

PageRuleData

Wrapper to allow better tracking of memory usage by page rule lists.

PageRuleMap

Stores page rules indexed by page names.

RevalidationSelectorAndHashes 🔒

SelectorMapEntry implementation for use in our revalidation selector map.

Rule

A rule, that wraps a style rule, but represents a single selector of the rule.

SavedContainingRuleState 🔒

ScopeBoundWithHashes

Start and end bound of a scope, along with their selector hashes.

ScopeBoundsWithHashes

Bounds for this scope, along with corresponding selector hashes.

ScopeConditionId

The id of a given scope condition, a sequentially-increasing identifier for a given style set.

ScopeConditionReference

Data required to process this scope condition.

ScopeRootCandidates

All potential sscope root candidates.

StylesheetContentsPtr 🔒

Stylist

This structure holds all the selectors and device characteristics for a given document. The selectors are converted into Rules and sorted into SelectorMaps keyed off stylesheet origin and pseudo-element (see CascadeData).

StylistSelectorVisitor 🔒

A selector visitor implementation that collects all the state the Stylist cares about a selector.

StylistStylesheetSet 🔒

A wrapper over a DocumentStylesheetSet that can be Sync, since it’s only used and exposed via mutable methods in the Stylist.

UA_CASCADE_DATA_CACHE 🔒

A cache of computed user-agent data, to be shared across documents.

UserAgentCascadeData 🔒

Enums

AuthorStylesEnabled

Whether author styles are enabled.

NestedDeclarationsContext 🔒

Nested declarations have effectively two behaviors:

RuleInclusion

What cascade levels to include when styling elements.

ScopeMatchesShadowHost 🔒

:scope selector, depending on the use case, can match a shadow host. If used outside of @scope, it cannot possibly match the host. Even when inside of @scope, it’s conditional if the selector will match the shadow host.

StylistImplicitScopeRoot 🔒

Implicit scope root, which may or may not be cached (i.e. For shadow DOM author styles that are cached and shared).

Traits

CascadeDataCacheEntry 🔒

Functions

compare_keyframes_in_same_layer 🔒

component_needs_revalidation 🔒

needs_revalidation_for_testing

A function to be able to test the revalidation stuff.

replace_parent_selector_with_implicit_scope

Replace any occurrence of parent selector in the given selector with a implicit scope selector.

scope_root_candidates

Find all scope conditions for a given condition ID, indexing into the given list of scope conditions.

scope_start_matches_shadow_host 🔒

Type Aliases

ElementAndPseudoRules 🔒

PartElementAndPseudoRules 🔒

PartMap 🔒

PrecomputedPseudoElementDeclarations 🔒

ReplacedSelectors 🔒

StyleSheetContentList 🔒

StylistSheet

The type of the stylesheets that the stylist contains.

UserAgentCascadeDataCache 🔒
