Struct SourceMapBuilder 

pub struct SourceMapBuilder { /* private fields */ }

Builder for constructing a SourceMap during code generation.

Implementations

impl SourceMapBuilder

pub fn new(logos_source: &str) -> Self

Create a new builder with the LOGOS source.

pub fn record_line(&mut self, logos_span: Span)

Record a mapping from current Rust line to LOGOS span.

pub fn record_line_at(&mut self, line: u32, logos_span: Span)

Record a mapping for an explicit Rust line — the post-hoc recording style used by mapped codegen, which counts emitted newlines instead of threading a cursor through every emission point.

pub fn record_var( &mut self, rust_name: &str, logos_name: Symbol, span: Span, role: OwnershipRole, )

Record a variable origin.

pub fn newline(&mut self)

Advance to the next line.

pub fn add_lines(&mut self, count: u32)

Add multiple newlines.

pub fn current_line(&self) -> u32

Get current line number.

pub fn build(self) -> SourceMap

Build the final source map.
