pub fn classify(
path: &Path,
src_roots: &[PathBuf],
path_rewrites: &[(PathBuf, PathBuf)],
cwd: Option<&Path>,
) -> PathLabelExpand description
Classify a resolved source path for the source pane title.
cwd is the directory the debugger was invoked from — paths under it
are displayed relative to it (e.g. src/lib.rs). src_roots are
tried next for workspace-relative display. path_rewrites handle
stdlib CI paths.
