pub fn parse_source_with_positions(
src: &str,
) -> Result<(Program, FnPositions), SyntaxError>Expand description
Variant of parse_source that also returns the byte-offset
position of each top-level fn declaration in src. Used by
the lex check CLI (and any other LLM-facing tooling) to stamp
source positions onto lex_types::PositionedErrors.
