pub struct RawIo { /* private fields */ }

Raw device I/O for Linux OS.

Trait Implementations

impl Drop for RawIoLinux

fn drop(&mut self)

Executes the destructor for this type.

impl RawIoOsIntf for RawIoLinux

fn new(path: &Path, create: bool, read: bool, write: bool) -> Result<Self>

Open a file or device.

fn get_sector_size(&self) -> Option<u32>

Get the physical sector size of the file or device. Returns None, if this is not a raw device.

fn drop_file_caches(&mut self, offset: u64, size: u64) -> Result<()>

Close the file, flush all buffers and drop all caches. This function ensures that subsequent reads are not read from RAM cache.

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

Close the file and flush all buffers. (This does not affect the caches).

fn sync(&mut self) -> Result<()>

Flush all buffers. (This does not affect the caches).

fn set_len(&mut self, size: u64) -> Result<()>

Truncate or extend the file length to the given size. This method is for unit testing only.

fn seek(&mut self, offset: u64) -> Result<u64>

Seek to a file offset.

fn read(&mut self, buffer: &mut [u8]) -> Result<RawIoResult>

Read a chunk of data.

fn write(&mut self, buffer: &[u8]) -> Result<RawIoResult>

Write a chunk of data.
