impl Filesystem for TestFilesystem

fn read_dir_diff_paths( &self, left: &Path, right: &Path, ) -> Result<BTreeSet<PathBuf>>

Find the set of files that appear in either left or right.

fn read_file_info(&self, path: &Path) -> Result<FileInfo>

Read the FileInfo for the provided path.

fn write_file(&mut self, path: &Path, contents: &str) -> Result<()>

Write new file contents to path.

fn copy_file(&mut self, old_path: &Path, new_path: &Path) -> Result<()>
