Struct Partition 

pub struct Partition { /* private fields */ }

A partition wrapper that provides access to a specific partition of a disk.

Implementations

impl Partition

pub fn new(disk: Disk, start_lba: u64, end_lba: u64) -> Self

Create a new partition wrapper.

pub fn size(&self) -> u64

Get the size of the partition.

pub fn position(&self) -> u64

Get the position of the cursor.

pub fn set_position(&mut self, pos: u64)

Set the position of the cursor.

pub fn read_one(&mut self, buf: &mut [u8]) -> DevResult<usize>

Read within one block, returns the number of bytes read.

pub fn write_one(&mut self, buf: &[u8]) -> DevResult<usize>

Write within one block, returns the number of bytes written.

Trait Implementations

impl BlockDevice for Partition

fn write( &mut self, buffer: &[u8], block_id: AbsoluteBN, count: u32, ) -> Ext4Result<()>

Writes count blocks from buffer starting at block_id.

fn read( &mut self, buffer: &mut [u8], block_id: AbsoluteBN, count: u32, ) -> Ext4Result<()>

Reads count blocks into buffer starting at block_id.

fn open(&mut self) -> Ext4Result<()>

Opens the underlying device.

fn close(&mut self) -> Ext4Result<()>

Closes the underlying device.

fn total_blocks(&self) -> u64

Returns the total number of device blocks.

fn current_time(&self) -> Ext4Result<Ext4Timestamp>

Returns the current timestamp used for inode metadata updates.

fn block_size(&self) -> u32

Returns the device block size in bytes.

fn flush(&mut self) -> Result<(), Ext4Error>

Flushes device state to stable storage.

fn is_open(&self) -> bool

Returns whether the device is currently open.

fn is_readonly(&self) -> bool

Returns whether the device is read-only.
