Expand description
Provides an iterator for rule list parsing.
Fields§
§input: &'a mut Parser<'i, 't>
The input given to RuleListParser::new
parser: P
The parser given to RuleListParser::new
Implementations§
source§impl<'i: 't, 't: 'a, 'a, R, P, E: 'i> RuleListParser<'i, 't, 'a, P>where
P: QualifiedRuleParser<'i, QualifiedRule = R, Error = E> + AtRuleParser<'i, AtRule = R, Error = E>,
impl<'i: 't, 't: 'a, 'a, R, P, E: 'i> RuleListParser<'i, 't, 'a, P>where
P: QualifiedRuleParser<'i, QualifiedRule = R, Error = E> + AtRuleParser<'i, AtRule = R, Error = E>,
sourcepub fn new_for_stylesheet(input: &'a mut Parser<'i, 't>, parser: P) -> Self
pub fn new_for_stylesheet(input: &'a mut Parser<'i, 't>, parser: P) -> Self
Create a new RuleListParser
for the given input
at the top-level of a stylesheet
and the given parser
.
The given parser
needs to implement both QualifiedRuleParser
and AtRuleParser
traits.
However, either of them can be an empty impl
since the traits provide default implementations of their methods.
The return type for finished qualified rules and at-rules also needs to be the same,
since <RuleListParser as Iterator>::next
can return either.
It could be a custom enum.
sourcepub fn new_for_nested_rule(input: &'a mut Parser<'i, 't>, parser: P) -> Self
pub fn new_for_nested_rule(input: &'a mut Parser<'i, 't>, parser: P) -> Self
Same is new_for_stylesheet
, but should be used for rule lists inside a block
such as the body of an @media
rule.
This differs in that <!--
and -->
tokens
should only be ignored at the stylesheet top-level.
(This is to deal with legacy work arounds for <style>
HTML element parsing.)

P: QualifiedRuleParser<'i, QualifiedRule = R, Error = E> + AtRuleParser<'i, AtRule = R, Error = E>,

P: QualifiedRuleParser<'i, QualifiedRule = R, Error = E> + AtRuleParser<'i, AtRule = R, Error = E>,
RuleListParser
is an iterator that yields Ok(_)
for a rule or Err(())
for an invalid one.
