Macros

with_all_bounds 🔒

with_bounds 🔒

Structs

AnPlusB

The properties that comprise an An+B syntax

AncestorHashes

Ancestor hashes for the bloom filter. We precompute these and store them inline with selectors to optimize cache performance during matching. This matters a lot.

AncestorIter 🔒

An iterator over all simple selectors belonging to ancestors.

CombinatorComposition 🔒

Composition of combinators in a given selector, not traversing selectors of pseudoclasses.

CombinatorIter 🔒

An iterator over all combinators in a selector. Does not traverse selectors within psuedoclasses.

LocalName

NthOfSelectorData

The properties that comprise an :nth- pseudoclass as of Selectors 4 (e.g., nth-child(An+B [of S]?)). https://www.w3.org/TR/selectors-4/#nth-child-pseudo

NthSelectorData

The properties that comprise an :nth- pseudoclass as of Selectors 3 (e.g., nth-child(An+B)). https://www.w3.org/TR/selectors-3/#nth-child-pseudo

RelativeSelector

Storage for a relative selector.

RelativeSelectorCombinatorCount

Count of combinators in a given relative selector, not traversing selectors of pseudoclasses.

Selector

A Selector stores a sequence of simple selectors and combinators. The iterator classes allow callers to iterate at either the raw sequence level or at the level of sequences of simple selectors separated by combinators. Most callers want the higher-level iterator.

SelectorIter

SelectorKey

Uniquely identify a selector based on its components, which is behind ThinArc and is therefore stable.

SelectorList

A selector list is a tagged pointer with either a single selector, or a ThinArc<()> of multiple selectors.

SelectorParsingState 🔒

Flags that indicate at which point of parsing a selector are we.

Enums

AttributeFlags 🔒

An attribute selector can have ‘s’ or ‘i’ as flags, or no flags at all.

Combinator

Component

A CSS simple selector or combinator. We store both in the same enum for optimal packing and cache performance, see [1].

ForgivingParsing 🔒

Whether or not we’re using forgiving parsing mode

MatchesFeaturelessHost

Whether a selector may match a featureless host element, and whether it may match other elements.

NthType

An enum for the different types of :nth- pseudoclasses

OptionalQName 🔒

ParseRelative

Flag indicating if we’re parsing relative selectors.

QNamePrefix 🔒

RelativeSelectorMatchHint

Flag indicating where a given relative selector’s match would be contained.

SelectorParseErrorKind

SimpleSelectorParseResult 🔒

Traits

NonTSPseudoClass

A trait that represents a pseudo-class.

Parser

PseudoElement

A trait that represents a pseudo-element.

SelectorImpl

This trait allows to define the parser implementation in regards of pseudo-classes/elements

Functions

collect_ancestor_hashes 🔒

collect_selector_hashes 🔒

is_css2_pseudo_element

Returns whether the name corresponds to a CSS2 pseudo-element that can be specified with the single colon syntax (in addition to the double-colon syntax, which can be used for all pseudo-elements).

namespace_empty_string

parse_attribute_flags 🔒

parse_attribute_selector 🔒

parse_compound_selector 🔒

simple_selector_sequence : [ type_selector | universal ] [ HASH | class | attrib | pseudo | negation ]* | [ HASH | class | attrib | pseudo | negation ]+

parse_functional_pseudo_class 🔒

parse_has 🔒

parse_inner_compound_selector 🔒

Parses one compound selector suitable for nested stuff like :-moz-any, etc.

parse_is_where 🔒

parse_negation 🔒

Level 3: Parse one simple_selector. (Though we might insert a second implied “|*” type selector.)

parse_nth_pseudo_class 🔒

parse_one_simple_selector 🔒

Parse a simple selector other than a type selector.

parse_qualified_name 🔒

Err(()): Invalid selector, abortOk(None(token)): Not a simple selector, could be something else. input was not consumed, but the token is still returned.Ok(Some(namespace, local_name)): None for the local name means a * universal selector

parse_selector 🔒

Build up a Selector. selector : simple_selector_sequence [ combinator simple_selector_sequence ]* ;

parse_simple_pseudo_class 🔒

parse_type_selector 🔒

Err(()): Invalid selector, abortOk(false): Not a type selector, could be something else. input was not consumed.Ok(true): Length 0 (*|*), 1 (*|E or ns|*) or 2 (|E or ns|E)

serialize_selector_list 🔒

to_ascii_lowercase 🔒

Returns a Cow::Borrowed if s is already ASCII lowercase, and a Cow::Owned if s had to be converted into ASCII lowercase.

try_parse_combinator 🔒
