pub struct ObfuscatedFileSystem { /* private fields */ }

[ObfuscatedFileSystem] is a special implementation of [FileSystem], which is used for constructing and simulating an abnormal file system for [Read] and [Write].

Implementations

impl ObfuscatedFileSystem

pub fn file_count(&self) -> usize

Trait Implementations

impl Default for ObfuscatedFileSystem

fn default() -> Self

Returns the “default value” for a type.

impl FileSystem for ObfuscatedFileSystem

type Handle = <DefaultFileSystem as FileSystem>::Handle

type Reader = ObfuscatedReader

type Writer = ObfuscatedWriter

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

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

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

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

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.

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

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