Struct PartRecord

pub struct PartRecord {
    pub boot_indicator: u8,
    pub start_head: u8,
    pub start_sector: u8,
    pub start_track: u8,
    pub os_type: u8,

    pub lb_size: u32,
}

A partition record, MBR-style.

Fields

boot_indicator: u8

Bit 7 set if partition is active (bootable)

start_head: u8

CHS address of partition start: 8-bit value of head in CHS address

start_sector: u8

CHS address of partition start: Upper 2 bits are 8th-9th bits of cylinder, lower 6 bits are sector

start_track: u8

CHS address of partition start: Lower 8 bits of cylinder

os_type: u8

Partition type. See https://www.win.tue.nl/~aeb/partitions/partition_types-1.html

end_head: u8

CHS address of partition end: 8-bit value of head in CHS address

end_sector: u8

CHS address of partition end: Upper 2 bits are 8th-9th bits of cylinder, lower 6 bits are sector

end_track: u8

CHS address of partition end: Lower 8 bits of cylinder

lb_start: u32

LBA of start of partition

lb_size: u32

Number of sectors in partition

Implementations

impl PartRecord

pub fn new_protective(lb_size: Option<u32>) -> Self

Create a protective Partition Record object with a specific disk size (in LB).

pub fn zero() -> Self

Create an all-zero Partition Record.

pub fn from_bytes(buf: &[u8]) -> Result<Self>

Parse input bytes into a Partition Record.

pub fn as_bytes(&self) -> Result<Vec<u8>>

Return the memory representation of this Partition Record as a byte vector.

Trait Implementations

impl Clone for PartRecord

fn clone(&self) -> PartRecord

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PartRecord

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

Formats the value using the given formatter.

impl PartialEq for PartRecord

fn eq(&self, other: &PartRecord) -> 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.
