}

A CHD V1/V2 header. V1 and V2 headers share a similar format with the only difference being V1 having a fixed 512-byte sector length, and V2 having an arbitrary sector length.

While all members of this struct are public, prefer the Header API over the fields of this struct.

Fields

version: Version

The CHD version (1, or 2).

length: u32

The length of the header.

flags: u32

CHD file flags.

compression: u32

The compression codec used in the CHD file. See CodecType for the valid codec types supported by this library.

hunk_size: u32

The size of each hunk in the CHD file in units of sector length.

total_hunks: u32

The total number of hunks in the CHD file.

cylinders: u32

The number of cylinders on the hard disk.

sectors: u32

The number of sectors on the hard disk.

heads: u32

The number of heads on the hard disk.

hunk_bytes: u32

The size of each hunk in the CHD file in bytes.

md5: [u8; 16]

The MD5 hash of the CHD file.

parent_md5: [u8; 16]

The MD5 hash of the parent CHD file.

unit_bytes: u32

The size of each unit in the CHD file in bytes.

unit_count: u64

The number of units in each hunk.

logical_bytes: u64

The logical size of the compressed data in bytes.

sector_length: u32

The length of each sector on the hard disk. For V1 CHD files, this will be 512. For V2, CHD files, this can be arbitrary.
