Structs

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.
LocalName
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
SelectorList
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].
OptionalQName 🔒
ParseErrorRecovery 🔒
How to treat invalid selectors in a selector list.
QNamePrefix 🔒
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 🔒
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_inner_compound_selector 🔒
Parses one compound selector suitable for nested stuff like :-moz-any, etc.
parse_is_or_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, abort
  • Ok(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, abort
  • Ok(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.
