Struct FileSystem

pub struct FileSystem { /* private fields */ }

A FAT16, virtual filesystem.

FAT-16 IS NOT case sensitive. All the paths will be silently converted to uppercase, as in any FAT system. It’s a TODO to support ext4.

Implementations

impl FileSystem

pub fn new(size: usize) -> Result<Self>

Creates a new filesystem with the provided partition size.

The memory buffer of the filesystem is lazy loaded; that is, it will allocate bytes as they are consumed.

pub fn try_to_bytes(&self) -> Result<Vec<u8>>

Serializes the structure into bytes.

pub fn try_from_bytes(bytes: &[u8]) -> Result<Self>

Deserializes the structure from bytes.

pub fn try_to_raw_device(&self) -> Result<Vec<u8>>

Serializes the raw device (MBR + FAT16) into bytes.

Note: this is a compatible filesystem that can be mounted elsewhere.

pub fn from_raw_device_unchecked(device: Vec<u8>) -> Self

Deserializes the raw device (MBR + FAT16) from bytes.

pub fn cwd(&self) -> &RelativePath

Returns the current work directory.

pub fn cd<P: AsRef<RelativePath>>(&mut self, dir: P) -> Result<()>

Navigates into the provided directory.

pub fn ls<P: AsRef<RelativePath>>(&self, path: P) -> Result<Vec<DirOrFile>>

List the contents of the path.

pub fn mkdir<P: AsRef<RelativePath>>(&mut self, dir: P) -> Result<()>

Creates the provided path recursively from the current directory.

pub fn rm<P: AsRef<RelativePath>>(&mut self, path: P) -> Result<()>

Removes a file or an empty directory.

pub fn open<P: AsRef<RelativePath>>(&mut self, path: P) -> Result<File>

Opens the file at the specified path.

If the file doesn’t exist, the flag File.new will be set to true.

pub fn save(&mut self, file: File) -> Result<()>

Saves the file into the buffer.

Creates the path recursively, if it doesn’t exist.

Trait Implementations

impl From<Device> for FileSystem

fn from(dev: Device) -> Self

Converts to this type from the input type.
