Information about the image supplied by QTI.

metadata: Option<Metadata>

Information about the image supplied by OEM.

hash_table: Vec<HashEntry>

Hashes of other segments in the ELF file.

qti_signature: Vec<u8>

QTI signature.

Implementations

impl HashTableSegment

pub fn parse(raw: &[u8]) -> Result<Self, ParseError>

Parse byte stream to hash table segment.

NOTE: The unparsed parts at the end of byte stream are considered padding.

Hint: Many *.mbn files are actually ELF files, please parse them via from_elf() instead of this function.

pub fn dump<W: Write>( &self, writer: &mut W, padding: bool, ) -> Result<(), ParseError>

Dump hash table segment to byte stream.

• padding: Write padding to byte stream or not.

pub fn len(&self) -> usize

Get the length of the segment in bytes.

pub fn adjust(&mut self, padding_to: usize)

Adjust field values of the MBN header to suitable values and the length of padding bytes.

• Padding_to: pad the segment to a specified size.

Trait Implementations

impl Clone for HashTableSegment

fn clone(&self) -> HashTableSegment

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HashTableSegment

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

Formats the value using the given formatter.
