Struct style::selector_parser::SelectorParser

pub struct SelectorParser<'a> {
    pub stylesheet_origin: Origin,
    pub namespaces: &'a Namespaces,
    pub url_data: Option<&'a UrlExtraData>,
}

Servo's selector parser.

Fields

stylesheet_origin: Origin

The origin of the stylesheet we're parsing.

namespaces: &'a Namespaces

The namespace set of the stylesheet.

url_data: Option<&'a UrlExtraData>

The extra URL data of the stylesheet, which is used to look up whether we are parsing a chrome:// URL style sheet.

Methods

impl<'a> SelectorParser<'a>

pub fn parse_author_origin_no_namespace(
    input: &str
) -> Result<SelectorList<SelectorImpl>, ParseError>

Parse a selector list with an author origin and without taking into account namespaces.

This is used for some DOM APIs like querySelector.

pub fn in_user_agent_stylesheet(&self) -> bool

Whether we're parsing selectors in a user-agent stylesheet.

pub fn chrome_rules_enabled(&self) -> bool

Whether we're parsing selectors in a stylesheet that has chrome privilege.

Trait Implementations

impl<'a> MallocSizeOf for SelectorParser<'a>

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl<'a, 'i> Parser<'i> for SelectorParser<'a>

type Impl = SelectorImpl

type Error = StyleParseErrorKind<'i>

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

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

fn parse_non_ts_functional_pseudo_class<'t>(
    &self,
    name: CowRcStr<'i>,
    parser: &mut CssParser<'i, 't>
) -> Result<NonTSPseudoClass, ParseError<'i>>

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

fn default_namespace(&self) -> Option<Namespace>

fn namespace_for_prefix(&self, prefix: &Prefix) -> Option<Namespace>

fn pseudo_element_allows_single_colon(name: &str) -> bool

Whether the name is a pseudo-element that can be specified with the single colon syntax in addition to the double-colon syntax.

fn parse_slotted(&self) -> bool

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

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