Header describing a GPT disk.

Fields

signature: String

GPT header magic signature, hardcoded to "EFI PART".

revision: u32

00 00 01 00

header_size_le: u32

little endian

crc32: u32

CRC32 of the header with crc32 section zeroed

reserved: u32

must be 0

current_lba: u64

For main header, 1

backup_lba: u64

LBA for backup header

first_usable: u64

First usable LBA for partitions (primary table last LBA + 1)

last_usable: u64

Last usable LBA (secondary partition table first LBA - 1)

disk_guid: Uuid

UUID of the disk

part_start: u64

Starting LBA of partition entries

num_parts: u32

Number of partition entries

part_size: u32

Size of a partition entry, usually 128

crc32_parts: u32

CRC32 of the partition table

Methods

impl Header[src]

pub fn write_primary(
    &self,
    file: &mut File,
    lb_size: LogicalBlockSize
) -> Result<usize>[src]

Write the primary header.

With a CRC32 set to zero this will set the crc32 after writing the header out.

pub fn write_backup(
    &self,
    file: &mut File,
    lb_size: LogicalBlockSize
) -> Result<usize>[src]

Write the backup header.

With a CRC32 set to zero this will set the crc32 after writing the header out.
