Expand description

Squashfs data extraction methods implemented over Read and Seek

Provided Methods§

Source

fn inodes( &mut self, superblock: &SuperBlock, kind: &Kind, ) -> Result<IntMap<u32, Inode>, BackhandError>

Parse Inode Table into Vec<(position_read, Inode)>

Source

fn root_inode( &mut self, superblock: &SuperBlock, kind: &Kind, ) -> Result<Inode, BackhandError>

Extract the root Inode as a BasicDirectory

Source

fn dir_blocks( &mut self, superblock: &SuperBlock, end_ptr: u64, kind: &Kind, ) -> Result<(IntMap<u64, u64>, Vec<u8>), BackhandError>

Parse required number of Metadatas uncompressed blocks required for Dirs

Source

fn fragments( &mut self, superblock: &SuperBlock, kind: &Kind, ) -> Result<Option<(u64, Vec<Fragment>)>, BackhandError>

Parse Fragment Table

Source

fn export( &mut self, _superblock: &SuperBlock, _kind: &Kind, ) -> Result<Option<(u64, Vec<Export>)>, BackhandError>

Parse Export Table

Source

fn uid( &mut self, superblock: &SuperBlock, kind: &Kind, ) -> Result<Vec<u16>, BackhandError>

Parse UID Table

Source

fn guid( &mut self, superblock: &SuperBlock, kind: &Kind, ) -> Result<Vec<u16>, BackhandError>

Parse GUID Table

Source

fn fragment_lookup_table( &mut self, superblock: &SuperBlock, seek: u64, size: u64, kind: &Kind, ) -> Result<(u64, Vec<Fragment>), BackhandError>

Parse Fragment Lookup Table (specialized for Fragment context)

Source

fn fragment_metadata_with_count( &mut self, superblock: &SuperBlock, seek: u64, count: u64, kind: &Kind, ) -> Result<Vec<Fragment>, BackhandError>

Parse count of Fragment Metadata blocks

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
