Struct DigestIdentifier 

pub struct DigestIdentifier { /* private fields */ }

Digest identifier with algorithm identification

The output contains:

• 1 byte: algorithm identifier
• N bytes: actual hash value (length depends on algorithm)

Implementations

impl DigestIdentifier

pub fn new(algorithm: HashAlgorithm, hash: Vec<u8>) -> Result<Self, CryptoError>

Create a new hash output

pub fn algorithm(&self) -> HashAlgorithm

Get the algorithm used

pub fn hash_bytes(&self) -> &[u8]

Get the hash bytes (without identifier)

pub fn hash_array<const N: usize>(&self) -> Result<[u8; N], CryptoError>

Get the hash as a fixed-size array

This method converts the hash bytes into an array of the specified size. The size must match the algorithm’s output length.

Errors

Returns an error if the requested size doesn’t match the algorithm’s output length.

Example

use ave_identity::{BLAKE3_HASHER, hash::{BLAKE3_OUTPUT_LENGTH, Hash}};

let hash = BLAKE3_HASHER.hash(b"Hello, World!");
let array: [u8; 32] = hash.hash_array().unwrap();
assert_eq!(array.len(), BLAKE3_OUTPUT_LENGTH);

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

Get the full bytes including algorithm identifier

pub fn from_bytes(bytes: &[u8]) -> Result<Self, CryptoError>

Parse from bytes (includes algorithm identifier)

pub fn verify(&self, data: &[u8]) -> bool

Verify that this hash matches the given data using the embedded algorithm

pub fn is_empty(&self) -> bool

Check if this is an empty digest (created via Default)

Returns true if the hash bytes are empty, which indicates this digest was created using Default::default().

Trait Implementations

impl BorshDeserialize for DigestIdentifier

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for DigestIdentifier

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for DigestIdentifier

fn clone(&self) -> DigestIdentifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DigestIdentifier

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

Formats the value using the given formatter.

impl Default for DigestIdentifier

fn default() -> Self

Creates an empty digest identifier using Blake3 algorithm

This is primarily useful for initialization purposes. Use is_empty() to check if a digest was created via default().

impl<'de> Deserialize<'de> for DigestIdentifier

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DigestIdentifier

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

Formats the value using the given formatter.

impl FromStr for DigestIdentifier

type Err = CryptoError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for DigestIdentifier

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for DigestIdentifier

fn cmp(&self, other: &DigestIdentifier) -> Ordering

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DigestIdentifier

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for DigestIdentifier

fn partial_cmp(&self, other: &DigestIdentifier) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for DigestIdentifier

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
