impl Fs for NativeFs

fn open<P: AsRef<Path>>(     &mut self,     path: P,     open_options: &OpenOptions ) -> Result<File>

Opens a file at path with the options specified by open_options.

fn canonicalize<P: AsRef<Path>>(&self, path: P) -> Result<PathBuf>

Returns the canonical, absolute form of a path with all intermediate components normalized and symbolic links resolved.

fn copy<P: AsRef<Path>, Q: AsRef<Path>>(     &mut self,     from: P,     to: Q ) -> Result<u64>

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

Creates a new, empty directory at the provided path.

fn create_dir_all<P: AsRef<Path>>(&mut self, path: P) -> Result<()>

Recursively create a directory and all of its parent components if they are missing.

fn hard_link<P: AsRef<Path>, Q: AsRef<Path>>(     &mut self,     src: P,     dst: Q ) -> Result<()>

Creates a new hard link on the filesystem.

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

Given a path, query the file system to get information about a file, directory, etc.

fn read<P: AsRef<Path>>(&self, path: P) -> Result<Vec<u8>>

Read the entire contents of a file into a bytes vector.

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

Returns an iterator over the entries within a directory.

fn read_link<P: AsRef<Path>>(&self, path: P) -> Result<PathBuf>

Reads a symbolic link, returning the file that the link points to.

fn read_to_string<P: AsRef<Path>>(&self, path: P) -> Result<String>

Read the entire contents of a file into a string.

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

Removes an existing, empty directory.

fn remove_dir_all<P: AsRef<Path>>(&mut self, path: P) -> Result<()>

Removes a directory at this path, after removing all its contents. Use carefully!

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

Removes a file from the filesystem.

fn rename<P: AsRef<Path>, Q: AsRef<Path>>(     &mut self,     from: P,     to: Q ) -> Result<()>

Rename a file or directory to a new name, replacing the original file if to already exists.

fn set_permissions<P: AsRef<Path>>(     &mut self,     path: P,     perm: Permissions ) -> Result<()>

Changes the permissions found on a file or a directory.

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

Query the metadata about a file without following symlinks.

fn write<P: AsRef<Path>, C: AsRef<[u8]>>(     &mut self,     path: P,     contents: C ) -> Result<()>

Write a slice as the entire contents of a file.

fn exists<P: AsRef<Path>>(&self, path: P) -> bool

Returns whether the path points at an existing entity.
