Struct Partition

pub struct Partition {
    pub part_type_guid: Type,
    pub part_guid: Uuid,
    pub first_lba: u64,
    pub last_lba: u64,
    pub flags: u64,
    pub name: String,
}

A partition entry in a GPT partition table.

Fields

part_type_guid: Type

GUID of the partition type.

part_guid: Uuid

UUID of the partition.

first_lba: u64

First LBA of the partition.

last_lba: u64

Last LBA of the partition.

flags: u64

Partition flags.

name: String

Partition name.

Implementations

impl Partition

pub fn zero() -> Self

Create a partition entry of type “unused”, whose bytes are all 0s.

pub fn write( &self, p: &Path, partition_index: u64, start_lba: u64, lb_size: LogicalBlockSize, ) -> Result<()>

Write the partition entry to the partitions area in the given file. NOTE: does not update partitions array crc32 in the headers!

pub fn write_to_device<D: DiskDevice>( &self, device: &mut D, partition_index: u64, start_lba: u64, lb_size: LogicalBlockSize, bytes_per_partition: u32, ) -> Result<()>

Write the partition entry to the partitions area in the given device. NOTE: does not update partitions array crc32 in the headers!

pub fn write_zero_entries_to_device<D: DiskDevice>( device: &mut D, starting_partition_index: u64, number_entries: u64, start_lba: u64, lb_size: LogicalBlockSize, bytes_per_partition: u32, ) -> Result<()>

Write empty partition entries starting at the given index in the partition array for the given number of entries…

pub fn bytes_len(&self, lb_size: LogicalBlockSize) -> Result<u64>

Return the length (in bytes) of this partition. Partition size is calculated as (last_lba + 1 - first_lba) * block_size Bounds are inclusive, meaning we add one to account for the full last logical block

pub fn bytes_start(&self, lb_size: LogicalBlockSize) -> Result<u64>

Return the starting offset (in bytes) of this partition.

pub fn is_used(&self) -> bool

Check whether this partition is in use.

pub fn size(&self) -> Result<u64>

Return the number of sectors in the partition.

Trait Implementations

impl Clone for Partition

fn clone(&self) -> Partition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Partition

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

Formats the value using the given formatter.

impl Display for Partition

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

Formats the value using the given formatter.

impl PartialEq for Partition

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