Struct SourceMap 

pub struct SourceMap { /* private fields */ }

Source map that tracks all mappings from Rust to Windjammer

Implementations

impl SourceMap

pub fn new() -> Self

Create a new empty source map

pub fn set_workspace_root(&mut self, root: impl Into<PathBuf>)

Set the workspace root for relative path calculation

pub fn add_mapping( &mut self, rust_file: impl Into<PathBuf>, rust_line: usize, rust_column: usize, wj_file: impl Into<PathBuf>, wj_line: usize, wj_column: usize, )

Add a mapping from Rust location to Windjammer location If a workspace root is set, paths are automatically converted to relative paths

pub fn lookup(&self, rust_file: &Path, rust_line: usize) -> Option<&Mapping>

Look up the Windjammer location for a given Rust location

pub fn lookup_fuzzy( &self, rust_file: &Path, rust_line: usize, ) -> Option<&Mapping>

Look up with fuzzy matching - finds the closest mapping if exact match not found

pub fn save_to_file(&self, path: impl AsRef<Path>) -> Result<(), Error>

Save the source map to a JSON file

pub fn load_from_file(path: impl AsRef<Path>) -> Result<Self, Box<dyn Error>>

Load a source map from a JSON file

pub fn len(&self) -> usize

Get the number of mappings in the source map

pub fn is_empty(&self) -> bool

Check if the source map is empty

pub fn mappings_for_wj_file(&self, wj_file: &Path) -> Vec<&Mapping>

Get all mappings for a specific Windjammer file

pub fn mappings_for_rust_file(&self, rust_file: &Path) -> Vec<&Mapping>

Get all mappings for a specific Rust file

pub fn get_location(&self, rust_line: usize) -> Option<Location>

Get the Windjammer location for a given Rust line (backward compatibility)

This is a convenience method that returns a Location struct instead of a Mapping. Used by error_mapper.rs for translating Rust compiler errors.

pub fn map_rust_to_windjammer( &self, rust_location: &Location, ) -> Option<Location>

Map a Rust location to a Windjammer location

This is the primary method used by error_mapper.rs to translate Rust compiler errors back to Windjammer source locations.
