Struct gpt::GptDisk

pub struct GptDisk<'a> { /* private fields */ }

A GPT disk backed by an arbitrary device.

Implementations

impl<'a> GptDisk<'a>

pub fn add_partition( &mut self, name: &str, size: u64, part_type: Type, flags: u64, part_alignment: Option<u64>, ) -> Result<u32>

Add another partition to this disk. This tries to find the optimum partition location with the lowest block device. Returns the new partition id if there was sufficient room to add the partition. Size is specified in bytes.

pub fn remove_partition( &mut self, id: Option<u32>, partguid: Option<Uuid>, ) -> Result<u32>

remove partition from this disk. This tries to find the partition based on either a given partition number (id) or a partition guid. Returns the partition id if the partition is removed

pub fn find_free_sectors(&self) -> Vec<(u64, u64)>

Find free space on the disk. Returns a tuple of (starting_lba, length in lba’s).

pub fn find_next_partition_id(&self) -> u32

Find next highest partition id.

pub fn primary_header(&self) -> Option<&Header>

Retrieve primary header, if any.

pub fn backup_header(&self) -> Option<&Header>

Retrieve backup header, if any.

pub fn partitions(&self) -> &BTreeMap<u32, Partition>

Retrieve partition entries.

pub fn guid(&self) -> &Uuid

Retrieve disk UUID.

pub fn logical_block_size(&self) -> &LogicalBlockSize

Retrieve disk logical block size.

pub fn update_disk_device( &mut self, device: DiskDeviceObject<'a>, writable: bool, ) -> DiskDeviceObject<'_>

Change the disk device that we are reading/writing from/to. Returns the previous disk device.

pub fn update_guid(&mut self, uuid: Option<Uuid>) -> Result<&Self>

Update disk UUID.

If no UUID is specified, a new random one is generated. No changes are recorded to disk until write() is called.

pub fn update_partitions( &mut self, pp: BTreeMap<u32, Partition>, ) -> Result<&Self>

Update current partition table.

No changes are recorded to disk until write() is called.

pub fn update_partitions_safe( &mut self, pp: BTreeMap<u32, Partition>, ) -> Result<&Self>

Update current partition table without touching backups

No changes are recorded to disk until write() is called.

pub fn update_partitions_embedded( &mut self, pp: BTreeMap<u32, Partition>, num_parts: u32, ) -> Result<&Self>

Update current partition table. Allows for changing the partition count, use with caution. No changes are recorded to disk until write() is called.

pub fn write(self) -> Result<DiskDeviceObject<'a>>

Persist state to disk, consuming this disk object.

This is a destructive action, as it overwrite headers and partitions entries on disk. All writes are flushed to disk before returning the underlying DiskDeviceObject.

pub fn write_inplace(&mut self) -> Result<()>

Persist state to disk, leaving this disk object intact.

This is a destructive action, as it overwrites headers and partitions entries on disk. All writes are flushed to disk before returning.

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

Formats the value using the given formatter.
