Struct RawFile 

pub struct RawFile { /* private fields */ }

Low-level reader for file content through raw disk cluster reads.

This type is Windows-only and intended for privileged scenarios where reading file extents directly from disk is required.

Implementations

impl RawFile

pub fn open<P: AsRef<Path>>(path: P) -> Result<Self>

Open a raw file reader with default tuning values.

Errors

Returns an error when:

• path is empty or not a drive-qualified path,
• source file metadata cannot be opened,
• raw volume metadata cannot be queried,
• retrieval pointer data is unavailable for the file.

pub fn builder() -> RawFileBuilder

Create a builder for opening a raw file reader.

This is the preferred entry point when custom read tuning is needed.

pub fn copy_to<P: AsRef<Path>>(&self, destination: P) -> Result<()>

Copy this source file into the given destination path.

The destination is created or truncated.

Errors

Returns an error when:

• the destination cannot be created,
• source data cannot be read from raw extents,
• destination writes or flush fail,
• the current process does not have required privileges.

Trait Implementations

impl Read for RawFile

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

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

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

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

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.

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

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

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

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

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

Reads the exact number of bytes required to fill buf.

fn read_buf(&mut self, buf: BorrowedCursor<'_>) -> Result<(), Error>

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

Pull some bytes from this source into the specified buffer.

fn read_buf_exact(&mut self, cursor: BorrowedCursor<'_>) -> Result<(), Error>

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

Reads the exact number of bytes required to fill cursor.

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

where Self: Sized,

Creates a “by reference” adapter for this instance of Read.

fn bytes(self) -> Bytes<Self>

where Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

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

where R: Read, Self: Sized,

Creates an adapter which will chain this stream with another.

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

where Self: Sized,

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

fn read_array<const N: usize>(&mut self) -> Result<[u8; N], Error>

where Self: Sized,

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

Read and return a fixed array of bytes from this source.
