Required Methods§

source

fn from_file( &self, file: Box<dyn VirtualFile> ) -> ForensicResult<Box<dyn VirtualFileSystem>>

Initializes a virtual filesystem from a file. Ex: a Zip FS from a file

source

fn from_fs( &self, fs: Box<dyn VirtualFileSystem> ) -> ForensicResult<Box<dyn VirtualFileSystem>>

Initializes a virtual filesystem from a filesyste. Ex: a remapping of windows routes to Linux routes.

source

fn read_to_string(&mut self, path: &Path) -> ForensicResult<String>

Read the entire contents of a file into a string.

source

fn read_all(&mut self, path: &Path) -> ForensicResult<Vec<u8>>

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

source

fn read( &mut self, path: &Path, pos: u64, buf: &mut [u8] ) -> ForensicResult<usize>

Read part of the content of a file into a bytes vector.

source

fn metadata(&mut self, path: &Path) -> ForensicResult<VMetadata>

Get the metadata of a file/dir

source

fn read_dir(&mut self, path: &Path) -> ForensicResult<Vec<VDirEntry>>

Lists the contents of a Directory

source

fn is_live(&self) -> bool

Check if the VirtualFileSystem is an abstraction over the real filesystem and not a virtual (like a ZIP file).

source

fn open(&mut self, path: &Path) -> ForensicResult<Box<dyn VirtualFile>>

Open a file

source

fn duplicate(&self) -> Box<dyn VirtualFileSystem>

Allows duplicating the existing file system
