Struct DebugInfo 

pub struct DebugInfo {
    pub source_map: SourceMap,
    pub line_numbers: Vec<(usize, u16, u32)>,
    pub variable_names: Vec<(u16, String)>,
    pub source_text: String,
}

Debug information for better error messages

Supports multi-file programs by tracking which file each instruction came from. This is essential for correct error reporting after modules are merged together.

Fields

source_map: SourceMap

Source file table for multi-file support

line_numbers: Vec<(usize, u16, u32)>

Line number mappings: (instruction_index, file_id, line_number) The file_id indexes into source_map.files

variable_names: Vec<(u16, String)>

Variable name mappings

source_text: String

Legacy: Source text for showing context in error messages Deprecated: Use source_map.source_texts instead

Implementations

impl DebugInfo

pub fn new(source_file: String) -> Self

Create a new DebugInfo with a single source file

pub fn add_line(&mut self, instruction_idx: usize, file_id: u16, line: u32)

Add a line number mapping for an instruction

pub fn get_location_for_instruction(&self, ip: usize) -> Option<(u16, u32)>

Get line number and file for an instruction index

pub fn get_line_for_instruction(&self, ip: usize) -> Option<u32>

Get line number for an instruction index (legacy, file_id=0)

pub fn get_source_line(&self, line: usize) -> Option<&str>

Get a source line by line number (1-indexed) from the primary file

pub fn get_source_line_from_file( &self, file_id: u16, line: usize, ) -> Option<&str>

Get a source line from a specific file

pub fn get_file_for_instruction(&self, ip: usize) -> Option<&str>

Get the file name for an instruction
