Implementations

impl Superblock

pub fn serialize(&self) -> Vec<u8>

Serialize this superblock to bytes.

Always writes v2/v3 format. Computes and appends Jenkins lookup3 checksum.

pub fn parse( data: &[u8], signature_offset: usize, ) -> Result<Superblock, FormatError>

Parse a superblock from data starting at signature_offset.

The signature must be present at the given offset.

Trait Implementations

fn clone(&self) -> Superblock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Superblock

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

Formats the value using the given formatter.

impl Eq for Superblock

impl PartialEq for Superblock

fn eq(&self, other: &Superblock) -> bool
