Struct Tag

pub struct Tag {
    pub text: Arc<String>,
    pub not: bool,
    pub inverted: bool,
    pub property: Option<Arc<String>>,
    pub debug_id: DebugId,
}

Expand description

Stores information about tag.

Fields§

§text: Arc<String>

The text to match against.

§not: bool

Whether to fail when matching against text.

§inverted: bool

Whether to set property to true or false (inverted).

§property: Option<Arc<String>>

Which property to set if tag matches.

§debug_id: DebugId

A debug id to track down the rule generating an error.

Implementations§

impl Tag

pub fn parse( &self, tokens: &mut Vec<Range<MetaData>>, state: &TokenizerState, read_token: &ReadToken<'_>, ) -> ParseResult<TokenizerState>

Parses tag. If the tag is linked to a property, the property will be set. If the meta reader fails setting the property the error is handled. If the token is not linked to any property, the same state will be returned.
