Enum ntfs::attribute_value::NtfsAttributeValue

pub enum NtfsAttributeValue<'n, 'f> {
    Resident(NtfsResidentAttributeValue<'f>),
    NonResident(NtfsNonResidentAttributeValue<'n, 'f>),
    AttributeListNonResident(NtfsAttributeListNonResidentAttributeValue<'n, 'f>),
}

Reader that abstracts over all attribute value types, returned by NtfsAttribute::value.

Variants

Resident(NtfsResidentAttributeValue<'f>)

A resident attribute value (which is entirely contained in the NTFS File Record).

NonResident(NtfsNonResidentAttributeValue<'n, 'f>)

A non-resident attribute value (whose data is in a cluster range outside the File Record).

AttributeListNonResident(NtfsAttributeListNonResidentAttributeValue<'n, 'f>)

A non-resident attribute value that is part of an Attribute List (and may span multiple connected attributes).

Implementations

impl<'n, 'f> NtfsAttributeValue<'n, 'f>

pub fn attach<'a, T>(
    self,
    fs: &'a mut T
) -> NtfsAttributeValueAttached<'n, 'f, 'a, T> where
    T: Read + Seek,

Returns a variant of this reader that implements Read and Seek by mutably borrowing the filesystem reader.

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 attribute does not have a Data Run, or
• The current Data Run is a “sparse” Data Run.

pub fn is_empty(&self) -> bool

Returns true if the attribute value contains no data.

pub fn len(&self) -> u64

Returns the total length of the attribute value data, in bytes.

Trait Implementations

impl<'n, 'f> Clone for NtfsAttributeValue<'n, 'f>

fn clone(&self) -> NtfsAttributeValue<'n, 'f>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'n, 'f> Debug for NtfsAttributeValue<'n, 'f>

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

Formats the value using the given formatter.

impl<'n, 'f> NtfsReadSeek for NtfsAttributeValue<'n, 'f>

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

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