Struct windows_drives::drive::BufferedPhysicalDrive

pub struct BufferedPhysicalDrive {
    pub sector_boundaries: (u64, u64),
    pub geometry: DiskGeometry,
    // some fields omitted
}

Gives buffered direct access to a physical drive to enable random access.

Also see PhysicalDrive.

Fields

sector_boundaries: (u64, u64)

The sector boundaries of the drive (e. g. to restrict access to a partition of the drive), where the first value of the tuple denotes the minimum and the second the maximum sector number (both inclusive). Calls to seek() will be considered relative to sector_boundaries.0 if seeking from the start or sector_boundaries.1 if seeking from the end.

NOTE: calls to geometry.size() will still return the size of the drive, regardless of the boundaries.

geometry: DiskGeometry

The DiskGeometry of the drive.

Implementations

impl BufferedPhysicalDrive

pub fn open(drive_num: u8) -> Result<Self, String>

Opens the physical drive with the given number.

NOTE: this requires administrator privileges.

Fails if an invalid drive number is given, the user has insufficient privileges or an error occures while opening the drive. If an error occurs, an error message containing the error number is returned, see here for a list.

pub fn open_bounded(
    drive_num: u8,
    boundaries: (u64, u64)
) -> Result<Self, String>

Trait Implementations

impl Debug for BufferedPhysicalDrive

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Read for BufferedPhysicalDrive

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

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

pub fn read_vectored(
    &mut self,
    bufs: &mut [IoSliceMut<'_>]
) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

pub fn is_read_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

pub unsafe fn initializer(&self) -> Initializer

🔬 This is a nightly-only experimental API. (read_initializer)

Determines if this Reader can work with buffers of uninitialized memory.

pub fn read_to_end(&mut self, buf: &mut Vec<u8, Global>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

pub fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, appending them to buf.

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

Read the exact number of bytes required to fill buf.

pub fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Read.

pub fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an Iterator over its bytes.

pub fn chain<R>(self, next: R) -> Chain<Self, R> where
    R: Read, 

Creates an adaptor which will chain this stream with another.

pub fn take(self, limit: u64) -> Take<Self>

Creates an adaptor which will read at most limit bytes from it.

impl Seek for BufferedPhysicalDrive

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

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

pub fn stream_len(&mut self) -> Result<u64, Error>

🔬 This is a nightly-only experimental API. (seek_convenience)

Returns the length of this stream (in bytes).

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

🔬 This is a nightly-only experimental API. (seek_convenience)

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