Required Methods

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

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

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

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

fn rename<'a>( &'a self, from: &'a Path, to: &'a Path, ) -> Pin<Box<dyn Future<Output = Result<(), FsError>> + Send + 'a>>

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

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

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<(), FsError>

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

Provided Methods

fn create_symlink(&self, _source: &Path, _target: &Path) -> Result<(), FsError>

fn hard_link(&self, _source: &Path, _target: &Path) -> Result<(), FsError>
