Struct massa_hash::HashXof

pub struct HashXof<const SIZE: usize>(pub [u8; SIZE]);

Extended Hash

Tuple Fields

0: [u8; SIZE]

Implementations

impl<const SIZE: usize> HashXof<SIZE>

pub fn from_bytes(bytes: &[u8; SIZE]) -> Self

From bytes

pub fn to_bytes(&self) -> &[u8; SIZE]

Transform into bytes

pub fn compute_from(data: &[u8]) -> HashXof<SIZE>

Compute from raw data

pub fn compute_from_tuple(data: &[&[u8]]) -> Self

Compute from tuple of byte arrays

pub fn to_bs58_check(&self) -> String

Serialize a Hash using bs58 encoding with checksum. Motivations for using base58 encoding:

base58_check is like base64 but-

• fully standardized (no = vs /)
• no weird characters (eg. +) only alphanumeric
• ambiguous letters combined (eg. O vs 0, or l vs 1)
• contains a checksum at the end to detect typing errors

Trait Implementations

impl<const SIZE: usize> BitXor for HashXof<SIZE>

type Output = HashXof<SIZE>

The resulting type after applying the ^ operator.

fn bitxor(self, other: Self) -> Self

Performs the ^ operation.

impl<const SIZE: usize> BitXorAssign for HashXof<SIZE>

fn bitxor_assign(&mut self, rhs: Self)

Performs the ^= operation.

impl<const SIZE: usize> Clone for HashXof<SIZE>

fn clone(&self) -> HashXof<SIZE>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<const SIZE: usize> Debug for HashXof<SIZE>

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

Formats the value using the given formatter.

impl<const SIZE: usize> Deserializer<HashXof<SIZE>> for HashXofDeserializer

fn deserialize<'a, E: ParseError<&'a [u8]> + ContextError<&'a [u8]>>( &self, buffer: &'a [u8], ) -> IResult<&'a [u8], HashXof<SIZE>, E>

Example

use massa_hash::{HashXof, HASH_XOF_SIZE_BYTES, HashXofDeserializer};
use massa_serialization::{Serializer, Deserializer, DeserializeError};

let hash_deserializer = HashXofDeserializer::new();
let hash: HashXof<HASH_XOF_SIZE_BYTES> = HashXof::compute_from(&"hello world".as_bytes());
let (rest, deserialized) = hash_deserializer.deserialize::<DeserializeError>(hash.to_bytes()).unwrap();
assert_eq!(deserialized, hash);
assert_eq!(rest.len(), 0);

impl<const SIZE: usize> Display for HashXof<SIZE>

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

Formats the value using the given formatter.

impl<const SIZE: usize> PartialEq for HashXof<SIZE>

fn eq(&self, other: &HashXof<SIZE>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<const SIZE: usize> Serializer<HashXof<SIZE>> for HashXofSerializer

fn serialize( &self, value: &HashXof<SIZE>, buffer: &mut Vec<u8>, ) -> Result<(), SerializeError>

Serialize a value T into a buffer of u8.
