Expand description

The data that the parser needs from outside in order to parse a stylesheet.

Fields§

§stylesheet_origin: Origin

The Origin of the stylesheet, whether it’s a user, author or user-agent stylesheet.

§url_data: &'a UrlExtraData

The extra data we need for resolving url values.

§rule_types: CssRuleTypes

The current rule types, if any.

§parsing_mode: ParsingMode

The mode to use when parsing.

§quirks_mode: QuirksMode

The quirks mode of this stylesheet.

§error_reporter: Option<&'a dyn ParseErrorReporter>

The active error reporter, or none if error reporting is disabled.

§namespaces: Cow<'a, Namespaces>

The currently active namespaces.

§use_counters: Option<&'a UseCounters>

The use counters we want to record while parsing style rules, if any.

Implementations§

source§

impl<'a> ParserContext<'a>

source

pub fn new( stylesheet_origin: Origin, url_data: &'a UrlExtraData, rule_type: Option<CssRuleType>, parsing_mode: ParsingMode, quirks_mode: QuirksMode, namespaces: Cow<'a, Namespaces>, error_reporter: Option<&'a dyn ParseErrorReporter>, use_counters: Option<&'a UseCounters> ) -> Self

Create a parser context.

source

pub fn nest_for_rule<R>( &mut self, rule_type: CssRuleType, cb: impl FnOnce(&mut Self) -> R ) -> R

Temporarily sets the rule_type and executes the callback function, returning its result.

source

pub fn in_page_rule(&self) -> bool

Whether we’re in a @page rule.

source

pub fn rule_types(&self) -> CssRuleTypes

Get the rule type, which assumes that one is available.

source

pub fn error_reporting_enabled(&self) -> bool

Returns whether CSS error reporting is enabled.

source

pub fn log_css_error( &self, location: SourceLocation, error: ContextualParseError<'_> )

Record a CSS parse error with this context’s error reporting.

source

pub fn in_ua_sheet(&self) -> bool

Whether we’re in a user-agent stylesheet.

source

pub fn chrome_rules_enabled(&self) -> bool

Returns whether chrome-only rules should be parsed.
