Struct texlang::token::trace::Tracer

pub struct Tracer { /* private fields */ }

Data structure that records information for token tracing

Implementations

impl Tracer

pub fn register_source_code( &mut self, token: Option<Token>, origin: Origin, source_code: &str, ) -> KeyRange

Registers source code with the tracer.

The returned KeyRange should be used to assign Keys to the tokens that are lexed from the referenced source code. The tracer assumes that the first key is assigned to token corresponding to the first UTF-8 character in their source code, the second key to the second UTF-8 character, and so on.

pub fn trace( &self, token: Token, cs_name_interner: &CsNameInterner, ) -> SourceCodeTrace

Return a trace for the provided token.

pub fn trace_end_of_input(&self) -> SourceCodeTrace
