Methods from Deref<Target = NodeInner>

pub fn data_layout(&self) -> InodeDataLayout

Returns the data layout of this node.

pub fn blkaddr_offset( &self, block_size: u64, offset: u64, ) -> Result<u64, ParsingError>

Safely calculate the on-disk offset for a read in this nodes data. This doesn’t check out of bounds errors.

pub fn metadata_end_offset(&self) -> Result<u64, ParsingError>

Offset immediately following this node’s metadata and inline xattrs.

pub fn compression_header(&self) -> Option<&CompressionHeader>

Returns the compression header for this node, if it has a compressed data layout.

pub fn compact_entry_pos( &self, block_size: u64, cluster_index: u64, ) -> Result<CompactEntry, ParsingError>

Returns the position and layout of a compact logical cluster index entry.

pub fn index_end_offset(&self, block_size: u64) -> Result<u64, ParsingError>

Offset immediately following the logical cluster index table. For files with inline data, this is where the inline data is stored.

pub fn total_lclusters(&self, lcluster_size: u64) -> u64

Returns the total number of logical clusters for this node.

pub fn size(&self) -> u64

pub fn ino(&self) -> u32

pub fn nid(&self) -> u64

pub fn link_count(&self) -> u32

pub fn uid(&self) -> u32

pub fn gid(&self) -> u32

pub fn mtime_ns(&self) -> u64

pub fn mode(&self) -> u16

pub fn storage_size(&self, block_size: u64) -> u64

Returns the storage size in bytes taken up by this node on disk.
