Trait Implementations§

impl FileSystem for DefaultFileSystem

type Handle = LogFd

type Reader = LogFile

type Writer = LogFile

fn create<P: AsRef<Path>>(&self, path: P) -> IoResult<Self::Handle>

fn open<P: AsRef<Path>>( &self, path: P, perm: Permission, ) -> IoResult<Self::Handle>

fn delete<P: AsRef<Path>>(&self, path: P) -> IoResult<()>

fn rename<P: AsRef<Path>>(&self, src_path: P, dst_path: P) -> IoResult<()>

fn new_reader(&self, handle: Arc<Self::Handle>) -> IoResult<Self::Reader>

fn new_writer(&self, handle: Arc<Self::Handle>) -> IoResult<Self::Writer>

fn reuse<P: AsRef<Path>>(&self, src_path: P, dst_path: P) -> Result<()>

Reuses file at src_path as a new file at dst_path. The default implementation simply renames the file.

fn reuse_and_open<P: AsRef<Path>>( &self, src_path: P, dst_path: P, ) -> Result<Self::Handle>

fn delete_metadata<P: AsRef<Path>>(&self, _path: P) -> Result<()>

Deletes user implemented metadata associated with path. Returns true if any metadata is deleted. Read more

fn exists_metadata<P: AsRef<Path>>(&self, _path: P) -> bool

Returns whether there is any user metadata associated with given path.
