Struct PartitionSet 

pub struct PartitionSet {
    pub table_kind: TableKind,
    pub partitions: Vec<Partition>,
    pub disk_size: u64,
    pub disk_guid: [u8; 16],
}

In-memory mutable partition set. All edits stay in this struct until commit writes them back.

Fields

table_kind: TableKind

partitions: Vec<Partition>

disk_size: u64

disk_guid: [u8; 16]

Disk GUID for the GPT header. Ignored when table_kind == Mbr.

Implementations

impl PartitionSet

pub fn from_probe(dev: &dyn BlockRead) -> Result<Self>

Probe the device and return its current partition set, ready for editing. The disk GUID for GPT is read from the on-disk header; for MBR it is left at all-zeros and unused.

pub fn empty_gpt(disk_size: u64) -> Self

Empty GPT table sized for disk_size bytes. Generates a v4 disk GUID.

pub fn empty_mbr(disk_size: u64) -> Self

Empty MBR table sized for disk_size bytes.

pub fn add( &mut self, start_hint: Option<u64>, length: u64, type_id: PartitionTypeId, label: Option<String>, ) -> Result<usize>

Add a partition. start_hint = None triggers a first-fit search at 1 MiB alignment. A non-None hint that isn’t already aligned is rounded up to the next 1 MiB boundary, and length is rounded up to the next sector if it isn’t already a multiple of 512.

Returns the index of the newly added partition.

pub fn remove(&mut self, target: PartitionRef) -> Result<()>

Remove a partition. Returns Error::Invalid if the ref doesn’t match anything.

pub fn resize(&mut self, target: PartitionRef, new_length: u64) -> Result<()>

Resize a partition. The new length is rounded up to a sector multiple and re-validated against the device bounds and other partitions.

pub fn commit(&self, dev: &dyn BlockDevice) -> Result<()>

Serialise to disk. Dispatches to the GPT or MBR writer depending on table_kind, then flushes the device.

Trait Implementations

impl Clone for PartitionSet

fn clone(&self) -> PartitionSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PartitionSet

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

Formats the value using the given formatter.
