Struct Device

pub struct Device { /* private fields */ }

A MBR FAT-16 compatible device emulator.

Implementations

impl Device

pub const MIN_SIZE: usize = 2_141_184usize

The minimum size in bytes supported by the FAT-16.

pub const MAX_SIZE: usize = 2_147_483_648usize

The maximum size in bytes supported by the FAT-16.

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

Attempts to create a new device with the provided amount of bytes.

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

Attempts to serialize the structure into raw device (MBR+part0) bytes.

The only failure is if the device is borrowed mutably elsewhere.

pub fn from_raw_bytes_unchecked(bytes: Vec<u8>) -> Self

Attempts to deserialize the structure from raw device (MBR+FAT16).

This device can be mounted using any fstools such as fdisk and mkfs.fat.

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

Serializes the structure into bytes.

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

Deserializes the structure into bytes.

pub fn with_min_len(self, min_len: usize) -> Self

Creates a device with the provided minimum length of the buffer.

pub fn with_max_len(self, max_len: usize) -> Self

Creates a device with the provided maximum length of the buffer.

pub fn with_resize_chunk(self, resize_chunk: usize) -> Self

Creates a device with the provided minimum chunk length increase.

pub fn open(self) -> VolumeManager<Self, Clock>

Opens the device into a MBR volumes manager.

Trait Implementations

impl BlockDevice for Device

type Error = Error

The errors that the BlockDevice can return. Must be debug formattable.

fn read( &self, blocks: &mut [Block], start_block_idx: BlockIdx, reason: &str, ) -> Result<()>

Read one or more blocks, starting at the given block index.

fn write(&self, blocks: &[Block], start_block_idx: BlockIdx) -> Result<()>

Write one or more blocks, starting at the given block index.

fn num_blocks(&self) -> Result<BlockCount>

Determine how many blocks this device can hold.

impl Clone for Device

fn clone(&self) -> Device

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for Device

fn default() -> Device

Returns the “default value” for a type.

impl From<Device> for FileSystem

fn from(dev: Device) -> Self

Converts to this type from the input type.
