Expand description

The parser for the top-level rules in a stylesheet.

Fields§

§shared_lock: &'a SharedRwLock

A reference to the lock we need to use to create rules.

§loader: Option<&'a dyn StylesheetLoader>

A reference to a stylesheet loader if applicable, for @import rules.

§context: ParserContext<'a>

The top-level parser context.

§state: State

The current state of the parser.

§dom_error: Option<RulesMutateError>

Whether we have tried to parse was invalid due to being in the wrong place (e.g. an @import rule was found while in the Body state). Reset to false when take_had_hierarchy_error is called.

§insert_rule_context: Option<InsertRuleContext<'a>>

The info we need insert a rule in a list.

§allow_import_rules: AllowImportRules

Whether @import rules will be allowed.

§declaration_parser_state: DeclarationParserState<'i>

Parser state for declaration blocks in either nested rules or style rules.

§error_reporting_state: Vec<SelectorList<SelectorImpl>>

State we keep around only for error reporting purposes. Right now that contains just the selectors stack for nesting, if any.

TODO(emilio): This isn’t populated properly for insertRule() but…

§rules: Vec<CssRule>

The rules we’ve parsed so far.

Implementations§

source§

impl<'a, 'i> TopLevelRuleParser<'a, 'i>

source

fn nested(&mut self) -> &mut NestedRuleParser<'a, 'i>

source

pub fn state(&self) -> State

Returns the current state of the parser.

source

fn check_state(&mut self, new_state: State) -> bool

Checks whether we can parse a rule that would transition us to new_state.

This is usually a simple branch, but we may need more bookkeeping if doing insertRule from CSSOM.
