Struct OpenLV 

pub struct OpenLV<'a, T> { /* private fields */ }

An open, byte-addressable view of a Logical Volume.

Implements embedded_io::Read + Seek. Reads map LV offsets to PV offsets via the segment table; only linear segments on the current PV are supported (anything else errors with OpenLvError::Unsupported).

Trait Implementations

impl<T: ErrorType> ErrorType for OpenLV<'_, T>

type Error = OpenLvError<<T as ErrorType>::Error>

Error type of all the IO operations on this type.

impl<T: Read + Seek> Read for OpenLV<'_, T>

fn read(&mut self, buf: &mut [u8]) -> Result<usize, Self::Error>

Read some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_exact( &mut self, buf: &mut [u8], ) -> Result<(), ReadExactError<Self::Error>>

Read the exact number of bytes required to fill buf.

impl<T: Read + Seek> Seek for OpenLV<'_, T>

fn seek(&mut self, pos: SeekFrom) -> Result<u64, Self::Error>

Seek to an offset, in bytes, in a stream.

fn rewind(&mut self) -> Result<(), Self::Error>

Rewind to the beginning of a stream.

fn stream_position(&mut self) -> Result<u64, Self::Error>

Returns the current seek position from the start of the stream.
