Struct DirItem 

pub struct DirItem {
    pub location: DiskKey,
    pub transid: u64,
    pub file_type: FileType,
    pub name: Vec<u8>,
    pub data: Vec<u8>,
}

Directory entry, stored as DIR_ITEM (hashed by name) or DIR_INDEX (sequential index) in the FS tree.

Multiple entries can be packed into a single item when names hash to the same value (for DIR_ITEM) or when processing xattrs (XATTR_ITEM).

Fields

location: DiskKey

Key of the target inode (objectid = inode number, type = INODE_ITEM).

transid: u64

Transaction ID when this entry was created.

file_type: FileType

Type of the referenced inode (file, directory, symlink, etc.).

name: Vec<u8>

Filename or xattr name (raw bytes).

data: Vec<u8>

Xattr value (empty for regular directory entries).

Implementations

impl DirItem

pub fn parse_all(data: &[u8]) -> Vec<Self>

Parse all packed directory entries from a single item’s data buffer.

pub fn serialize( location: &DiskKey, transid: u64, file_type: u8, name: &[u8], ) -> Vec<u8>

Serialize a directory entry.

On-disk layout: location key (17) + transid (8) + data_len (2) + name_len (2) + type (1) + name + data = 30 + name.len() + data.len().

Trait Implementations

impl Clone for DirItem

fn clone(&self) -> DirItem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DirItem

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

Formats the value using the given formatter.
