}

Inode metadata, stored as INODE_ITEM in the FS tree.

Contains POSIX attributes (uid, gid, mode, timestamps) plus btrfs-specific fields (flags, sequence number, block group hint).

Fields

generation: u64

Generation when this inode was created.

transid: u64

Transaction ID of the last modification.

size: u64

Logical file size in bytes.

nbytes: u64

Total on-disk bytes used (including all copies for RAID).

block_group: u64

Block group hint for new allocations.

nlink: u32

Hard link count.

uid: u32

Owner user ID.

gid: u32

Owner group ID.

mode: u32

POSIX file mode (type + permissions).

rdev: u64

Device number (for character/block device inodes).

flags: InodeFlags

Inode flags (NODATASUM, COMPRESS, etc.).

sequence: u64

NFS-compatible change sequence number.

atime: Timespec

Last access time.

ctime: Timespec

Last change time (inode metadata).

mtime: Timespec

Last modification time (file data).

otime: Timespec

Creation time.

Implementations

impl InodeItem

pub fn parse(data: &[u8]) -> Option<Self>

Parse an inode item from a raw byte buffer. Returns None if the buffer is too small.

Trait Implementations

impl Clone for InodeItem

fn clone(&self) -> InodeItem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InodeItem

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

Formats the value using the given formatter.
