Implementations

impl<R: Read + Seek> DirReader<R>

pub fn new(inode_reader: InodeReader<R>) -> Self

Wrap an InodeReader to provide directory-level access.

pub fn inode_reader(&self) -> &InodeReader<R>

Borrow the underlying InodeReader.

pub fn inode_reader_mut(&mut self) -> &mut InodeReader<R>

Mutably borrow the underlying InodeReader.

pub fn read_dir(&mut self, dir_ino: u64) -> Result<Vec<DirEntry>>

Read all (live) directory entries from inode dir_ino.

Reads the inode’s data blocks and calls parse_dir_block on each block-sized chunk, then filters out deleted entries (inode == 0).

pub fn lookup(&mut self, dir_ino: u64, name: &[u8]) -> Result<Option<u64>>

Look up a single name in directory inode dir_ino.

Returns Ok(Some(ino)) when found, Ok(None) when not found.

pub fn resolve_path(&mut self, path: &str) -> Result<u64>

Resolve an absolute path to an inode number.

Always starts at inode 2 (root). Follows symlinks up to MAX_SYMLINK_DEPTH times. Returns Ext4Error::PathNotFound when any component is missing.

pub fn read_link(&mut self, ino: u64) -> Result<Vec<u8>>

Read the target of a symlink inode.

For short symlinks (size <= 60 and no extents), the path is stored inline in i_block. Otherwise it is read from the data blocks.
