Struct sqruff_lib::core::parser::lexer::StringLexer

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

This singleton matcher matches strings exactly. This is the simplest usable matcher, but it also defines some of the mechanisms for more complicated matchers, which may simply override the _match function rather than the public match function. This acts as the base class for matchers.

Implementations

impl<SegmentArgs: Clone + Debug + Sync> StringLexer<SegmentArgs>

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

impl<SegmentArgs: Clone + Debug + Sync> Matcher for StringLexer<SegmentArgs>

fn match_(&self, forward_string: &str) -> Result<LexMatch, ValueError>

Given a string, match what we can and return the rest.

fn get_name(&self) -> String

The name of the matcher.
