Struct PreprocessOutcome 

pub struct PreprocessOutcome {
    pub result: OpyResult<(Preprocessed, Vec<FileRecord>)>,
    pub files: Vec<FileRecord>,
    pub display_root: PathBuf,
    pub warnings: Vec<PreprocessWarning>,
}

The outcome of preprocessing with overlays, retaining the file registry registered so far even when a directive or expansion fails, so callers can map an error’s span file id to its actual source.

Fields

result: OpyResult<(Preprocessed, Vec<FileRecord>)>

files: Vec<FileRecord>

display_root: PathBuf

The directory the file-registry display_paths resolve against — the #!mainFile effective directory when the first line redirects the project root, otherwise the canonicalized input root.

warnings: Vec<PreprocessWarning>
