Struct DmgReader 

pub struct DmgReader<R> { /* private fields */ }

DMG reader for parsing and extracting disk images

Implementations

impl<R: Read + Seek> DmgReader<R>

pub fn new(reader: R) -> Result<Self>

Create a new DMG reader with default options (checksum verification enabled)

pub fn with_options(reader: R, options: DmgReaderOptions) -> Result<Self>

Create a new DMG reader with custom options

pub fn koly(&self) -> &KolyHeader

Get the koly header

pub fn partitions(&self) -> &[PartitionEntry]

Get all partitions

pub fn partition(&self, name: &str) -> Option<&PartitionEntry>

Get partition by name

pub fn list_partitions(&self) -> Vec<&str>

List all partition names

pub fn stats(&self) -> DmgStats

Get DMG statistics

pub fn decompress_partition(&mut self, partition_id: i32) -> Result<Vec<u8>>

Decompress a specific partition to raw disk data

pub fn decompress_partition_to<W: Write>( &mut self, partition_id: i32, writer: &mut W, ) -> Result<u64>

Decompress a partition and stream to a writer block-by-block. Only uses ~block_size memory per block instead of buffering the full partition. Integrity is ensured by koly checksums verified on open. Returns the total number of bytes written.

pub fn decompress_main_partition(&mut self) -> Result<Vec<u8>>

Decompress the main HFS+ partition (largest one)

pub fn decompress_main_partition_to<W: Write>( &mut self, writer: &mut W, ) -> Result<u64>

Stream the main HFS+/APFS partition to a writer.

pub fn main_partition_id(&self) -> Result<i32>

Find the partition ID of the main HFS+/APFS partition.

pub fn hfs_partition_id(&self) -> Result<i32>

Find the partition ID of the main HFS+/HFSX partition (excludes APFS). Returns Err(FileNotFound) if no HFS-compatible partition exists.

pub fn decompress_all(&mut self) -> Result<Vec<u8>>

Decompress all partitions into a single raw disk image

pub fn decompress_partition_auto( &mut self, partition_id: i32, ) -> Result<Vec<u8>>

Decompress a specific partition to raw disk data.

Automatically uses parallel decompression when the parallel feature is enabled.

pub fn decompress_main_partition_auto(&mut self) -> Result<Vec<u8>>

Decompress the main HFS+ partition using auto-selected strategy.

pub fn decompress_main_partition_to_auto<W: Write>( &mut self, writer: &mut W, ) -> Result<u64>

Stream the main HFS+/APFS partition to a writer, using auto-selected strategy.

pub fn compression_info(&self) -> CompressionInfo

Get info about block compression types used

impl DmgReader<BufReader<File>>

pub fn open<P: AsRef<Path>>(path: P) -> Result<Self>

Open a DMG file from a path with default options (checksum verification enabled)

pub fn open_with_options<P: AsRef<Path>>( path: P, options: DmgReaderOptions, ) -> Result<Self>

Open a DMG file from a path with custom options
