Struct RawIo

pub struct RawIo { /* private fields */ }

Raw device I/O abstraction.

Implementations

impl RawIo

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

Open a file or device.

pub 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.

pub fn drop_file_caches(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.

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

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

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

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

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

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

Seek to a file offset.

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

Read a chunk of data.

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

Write a chunk of data.
