Per-file metadata captured from a kHFSPlusFileRecord.

Fields

name: String

name_utf16: Vec<u16>

cnid: u32

Source CNID (fileID).

parent_cnid: u32

flags: u16

finder_info: [u8; 16]

userInfo — 16 bytes of FileInfo (FInfo). fdType at byte 0 and fdCreator at byte 4 are the type/creator codes; fdFlags at byte 8 is the Finder flags word (0x8000 = kIsAlias).

extended_finder_info: [u8; 16]

finderInfo — 16 bytes of ExtendedFileInfo (FXInfo).

bsd_info: [u8; 16]

permissions — 16 bytes of HFSPlusBSDInfo (zeros on most volumes).

create_date: u32

content_mod_date: u32

attribute_mod_date: u32

access_date: u32

backup_date: u32

text_encoding: u32

data_fork_raw: [u8; 80]

Raw 80-byte HFSPlusForkData for the data fork (8 inline extents + logical/total/clump). Resolved into a streaming reader via HfsPlusFilesystem::fork_stream_reader at clone time so the bytes never have to materialise in RAM.

rsrc_fork_raw: [u8; 80]

Raw 80-byte HFSPlusForkData for the resource fork.

data_fork_size: u64

Logical data-fork size in bytes (mirror of bytes 0..8 of data_fork_raw, broken out for convenience).

rsrc_fork_size: u64

Logical resource-fork size in bytes.

is_inode: bool

true for files that live under the source’s HFS+ Private Data directory whose name parses as iNode<N> — i.e. file-hardlink inodes. Replay must emit them through create_hardlink_inode rather than as ordinary files in the user-visible tree, and the hardlink stubs that reference them carry the source CNID stored here. Always false until SourceCatalogSnapshot::capture resolves the private dir.

inode_num: Option<u32>

Source iNodeNum (decoded from the iNode<N> filename) for inode rows; None for ordinary files. Carried so the replay path can emit each hardlink stub with the same iNodeNum the inode itself will be created under on the target.

Implementations

Decoded type code (FInfo bytes 0..4) as a 4-character string.

pub fn creator_code(&self) -> String
