Implementations

impl IncrementalCache

pub fn new(cache_dir: &Path) -> Result<Self>

Create a new cache manager.

cache_dir will be created if it does not exist.

pub fn process_file( &self, file_path: &Path, relative_path: &str, parse_fn: ParseFn, ) -> Result<FileFacts>

Process a single source file.

• file_path – absolute path to the source file.
• relative_path – the path that will be used in the cache name (usually the path relative to the project root).
• parse_fn – a boxed closure that parses the source and returns facts; it is called only if the file has changed or is not cached.

Returns FileFacts containing the extracted or cached facts.

fn cache_paths(&self, relative_path: &str) -> (PathBuf, PathBuf)
