Struct sqruff_lib::core::parser::lexer::RegexLexer

pub struct RegexLexer<SegmentArgs: 'static + Clone> { /* private fields */ }

This RegexLexer matches based on regular expressions.

Implementations

impl<SegmentArgs: Clone + Debug> RegexLexer<SegmentArgs>

pub fn new( name: &'static str, regex: &str, segment_constructor: SegmentConstructorFn<SegmentArgs>, segment_args: SegmentArgs, sub_divider: Option<Box<dyn Matcher>>, trim_post_subdivide: Option<Box<dyn Matcher>> ) -> Result<Self, Error>

pub fn _match(&self, forward_string: &str) -> Option<LexedElement>

Use regexes to match chunks.
