    // Required methods
    fn read_dir(&self, path: &Path) -> Result<ReadDir>;
    fn create_dir(&self, path: &Path) -> Result<()>;

Required Methods

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

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

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

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

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

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

fn new_open_options(&self) -> OpenOptions

Provided Methods

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.
