Struct zff::header::version1::HashHeader

pub struct HashHeader { /* private fields */ }

Header for the hash values of the dumped data stream. This header is part of the main header and contains 0 or more hash values of the dumped data.\

Implementations

impl HashHeader

pub fn new(version: u8, hashes: Vec<HashValue>) -> HashHeader

creates a new HashHeader by given values/hashes.

pub fn hash_values(&self) -> &Vec<HashValue>

returns a reference to the underlying HashValues.

Trait Implementations

impl Clone for HashHeader

fn clone(&self) -> HashHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HashHeader

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

Formats the value using the given formatter.

impl HeaderCoding for HashHeader

type Item = HashHeader

the return value for decode_content(), decode_directly(), decode_for_key();

fn identifier() -> u32

returns the identifier (=Magic bytes) of the header.

fn version(&self) -> u8

returns the version of the header.

fn encode_header(&self) -> Vec<u8>

encodes the header.

fn encode_directly(&self) -> Vec<u8>

encodes the (header) value/object directly (= without key).

fn encode_for_key<K: Into<String>>(&self, key: K) -> Vec<u8>

encodes a key to the (header) value/object.

fn decode_content(data: Vec<u8>) -> Result<HashHeader>

decodes the content of the header.

fn header_size(&self) -> usize

returns the size of the encoded header (in bytes)

fn encode_key<K: Into<String>>(key: K) -> Vec<u8>

encodes a given key.

fn decode_header_length<R: Read>(data: &mut R) -> Result<u64>

decodes the length of the header.

fn check_identifier<R: Read>(data: &mut R) -> bool

checks if the read identifier is valid for this header.

fn check_key_on_position<K: Into<String>, R: Read>(data: &mut R, key: K) -> bool

helper method to check, if the key is on position.

fn decode_directly<R: Read>(data: &mut R) -> Result<Self::Item>

decodes the header directly.

fn decode_for_key<K: Into<String>, R: Read>(
    data: &mut R,
    key: K
) -> Result<Self::Item>

decodes the header for the given key.
