Trait Implementations

impl Debug for MountFileSystem

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MountFileSystem

fn default() -> Self

Returns the “default value” for a type.

impl FileOpener for MountFileSystem

fn open( &self, path: &Path, conf: &OpenOptionsConfig, ) -> Result<Box<dyn VirtualFile + Send + Sync>>

impl FileSystem for MountFileSystem

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

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

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

fn create_symlink(&self, source: &Path, target: &Path) -> Result<()>

fn hard_link(&self, source: &Path, target: &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<()>
