Struct ntfs::attribute_value::NtfsDataRun

pub struct NtfsDataRun { /* private fields */ }

A single NTFS Data Run, which is a continuous cluster range of a non-resident value.

A Data Run’s size is a multiple of the cluster size configured for the filesystem. However, a Data Run does not know about the actual size used by data. This information is only available in the corresponding attribute. Keep this in mind when doing reads and seeks on data runs. You may end up on allocated but unused data.

Implementations

impl NtfsDataRun

pub fn allocated_size(&self) -> u64

Returns the allocated size of the Data Run, in bytes.

pub fn data_position(&self) -> NtfsPosition

Returns the absolute current data seek position within the filesystem, in bytes. This may be None if:

• The current seek position is outside the valid range, or
• The Data Run is a “sparse” Data Run

Trait Implementations

impl Clone for NtfsDataRun

fn clone(&self) -> NtfsDataRun

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NtfsDataRun

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

Formats the value using the given formatter.

impl NtfsReadSeek for NtfsDataRun

fn read<T>(&mut self, fs: &mut T, buf: &mut [u8]) -> Result<usize>where T: Read + Seek,

See std::io::Read::read.

fn seek<T>(&mut self, _fs: &mut T, pos: SeekFrom) -> Result<u64>where T: Read + Seek,

See std::io::Seek::seek.

fn stream_position(&self) -> u64

See std::io::Seek::stream_position.

fn read_exact<T>(&mut self, fs: &mut T, buf: &mut [u8]) -> Result<()>where T: Read + Seek,

See std::io::Read::read_exact.

impl PartialEq<NtfsDataRun> for NtfsDataRun

fn eq(&self, other: &NtfsDataRun) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
