}

Parsed NTFS boot sector geometry.

Fields

bytes_per_sector: u16

Bytes per logical sector (power of two, 256..=4096; typically 512).

sectors_per_cluster: u8

Logical sectors per cluster (power of two; typically 8).

total_sectors: u64

Total number of sectors in the volume.

mft_lcn: u64

Cluster number (LCN) of the $MFT.

mftmirr_lcn: u64

Cluster number (LCN) of the $MFTMirr.

mft_record_size: u64

Size of one MFT file-record segment, in bytes (typically 1024).

index_record_size: u64

Size of one index buffer, in bytes (typically 4096).

volume_serial: u64

64-bit volume serial number.

Implementations

impl BootSector

pub fn cluster_size(&self) -> u64

Cluster size in bytes (bytes_per_sector × sectors_per_cluster).

pub fn mft_byte_offset(&self) -> u64

Absolute byte offset of the $MFT within the volume.

pub fn mftmirr_byte_offset(&self) -> u64

Absolute byte offset of the $MFTMirr within the volume.

pub fn parse(sector: &[u8]) -> Result<BootSector>

Parse an NTFS boot sector from the start of a volume.

Errors

Returns NtfsError::TooShort if sector is smaller than the BPB, NtfsError::BadOemId if it is not an NTFS volume, and the various Bad* variants for out-of-range geometry fields.

Trait Implementations

impl Clone for BootSector

fn clone(&self) -> BootSector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BootSector

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

Formats the value using the given formatter.

impl Eq for BootSector

impl PartialEq for BootSector

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

Tests for self and other values to be equal, and is used by ==.

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

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