Struct windows_drives::drive::PhysicalDrive

pub struct PhysicalDrive {
    pub geometry: DiskGeometry,
    // some fields omitted
}

Gives direct access to a physical drive.

NOTE: because of Win32 restrictions, you must read() whole sectors and must only seek to sector boundaries. If you need random access, use BufferedPhysicalDrive.

Fields

geometry: DiskGeometry

The DiskGeometry of the drive.

Implementations

impl PhysicalDrive

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.

Trait Implementations

impl Debug for PhysicalDrive

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

Formats the value using the given formatter.

impl Drop for PhysicalDrive

pub fn drop(&mut self)

Executes the destructor for this type.

impl Read for PhysicalDrive

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 PhysicalDrive

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.
