Contains traditional inode data and attributes.

Fields

generation: U64<LE>

transid: U64<LE>

size: U64<LE>

The size of a file, in bytes.

nbytes: U64<LE>

The size allocated to the file, in bytes.

This is equal to the sum of all of the extent data for the inode. This is 0 for directories.

block_group: U64<LE>

This contains the byte offset of a block group when structure is a free space inode.

This value is unused for normal inodes.

nlink: U32<LE>

Count of inode references for the inode.

When used outside of a file tree, this value is 1.

uid: U32<LE>

The user ID of the owner in Unix.

gid: U32<LE>

The group ID of the group owner in Unix.

mode: U32<LE>

The Unix protection mode.

rdev: U64<LE>

The device identifier (if a special file).

flags: U64<LE>

Flags for the inode. See [InodeFlags] for values.

sequence: U64<LE>

A sequence number used for compatibility with NFS.

This value is initialized to 0 and incremented each time mtime is updated.

_unused: [u64; 4]

atime: Time

Timestamp of the last access to the inode.

ctime: Time

Timestamp of the last change to the inode's properties.

mtime: Time

Timestamp of the last change to the inode's contents.

otime: Time

Timestamp of the creation of the inode.
