Required Methods

fn readlink(&self, path: &Path) -> Result<PathBuf>

fn read_dir(&self, path: &Path) -> Result<ReadDir>

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

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

fn rename<'a>( &'a self, from: &'a Path, to: &'a Path, ) -> BoxFuture<'a, Result<()>>

fn metadata(&self, path: &Path) -> Result<Metadata>

fn symlink_metadata(&self, path: &Path) -> Result<Metadata>

This method gets metadata without following symlinks in the path. Currently identical to metadata because symlinks aren’t implemented yet.

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

fn new_open_options(&self) -> OpenOptions<'_>

fn mount( &self, name: String, path: &Path, fs: Box<dyn FileSystem + Send + Sync>, ) -> Result<()>
