Required Associated Types

type Impl: SelectorImpl

type Error: 'i + From<SelectorParseErrorKind<'i>>

Provided Methods

fn parse_slotted(&self) -> bool

Whether to parse the ::slotted() pseudo-element.

fn parse_part(&self) -> bool

Whether to parse the ::part() pseudo-element.

fn parse_nth_child_of(&self) -> bool

Whether to parse the selector list of nth-child() or nth-last-child().

fn parse_is_and_where(&self) -> bool

Whether to parse :is and :where pseudo-classes.

fn parse_has(&self) -> bool

Whether to parse the :has pseudo-class.

fn parse_parent_selector(&self) -> bool

Whether to parse the ‘&’ delimiter as a parent selector.

fn is_is_alias(&self, _name: &str) -> bool

Whether the given function name is an alias for the :is() function.

fn parse_host(&self) -> bool

Whether to parse the :host pseudo-class.

fn allow_forgiving_selectors(&self) -> bool

Whether to allow forgiving selector-list parsing.

fn parse_non_ts_pseudo_class( &self, location: SourceLocation, name: CowRcStr<'i>, ) -> Result<<Self::Impl as SelectorImpl>::NonTSPseudoClass, ParseError<'i, Self::Error>>

This function can return an “Err” pseudo-element in order to support CSS2.1 pseudo-elements.

fn parse_pseudo_element( &self, location: SourceLocation, name: CowRcStr<'i>, ) -> Result<<Self::Impl as SelectorImpl>::PseudoElement, ParseError<'i, Self::Error>>

fn parse_functional_pseudo_element<'t>( &self, name: CowRcStr<'i>, arguments: &mut CssParser<'i, 't>, ) -> Result<<Self::Impl as SelectorImpl>::PseudoElement, ParseError<'i, Self::Error>>

fn default_namespace( &self, ) -> Option<<Self::Impl as SelectorImpl>::NamespaceUrl>

fn namespace_for_prefix( &self, _prefix: &<Self::Impl as SelectorImpl>::NamespacePrefix, ) -> Option<<Self::Impl as SelectorImpl>::NamespaceUrl>
