Struct GptPartitionEntryArray

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

Storage for a GPT partition entry array.

Implementations

impl<'a> GptPartitionEntryArray<'a>

pub fn new( layout: GptPartitionEntryArrayLayout, block_size: BlockSize, storage: &'a mut [u8], ) -> Result<Self, GptPartitionEntryArrayError>

Create a new GptPartitionEntryArray with the given layout. The length of storage must be at least layout.num_bytes_rounded_to_block.

pub fn storage(&self) -> &[u8]

Get a reference to the storage buffer.

pub fn storage_mut(&mut self) -> &mut [u8]

Get a mutable reference to the storage buffer.

pub fn layout(&self) -> &GptPartitionEntryArrayLayout

Get the partition entry array layout.

pub fn set_start_lba(&mut self, start_lba: Lba)

Change the partition entry array’s start Lba.

pub fn get_partition_entry(&self, index: u32) -> Option<&GptPartitionEntry>

Available on crate feature bytemuck only.

Get a partition entry reference. The index is zero-based.

pub fn get_partition_entry_mut( &mut self, index: u32, ) -> Option<&mut GptPartitionEntry>

Available on crate feature bytemuck only.

Get a mutable partition entry reference. The index is zero-based.

pub fn calculate_crc32(&self) -> Crc32

Calculate the CRC32 checksum for the partition entry array. The return value can then be set in the GptHeader::partition_entry_array_crc32 field.
