Struct Hash 

#[repr(transparent)]
pub struct Hash(pub [u8; 32]);

A hash wrapper.

A hash is often provided as string composed of 64 hexadecimal character (0 to 9 then A to F).

Tuple Fields

0: [u8; 32]

Implementations

impl Hash

pub const SIZE_IN_BYTES: usize = 32usize

Hash size (in bytes).

pub fn random() -> Result<Self, UnspecifiedRandError>

Generate a random Hash

pub fn compute(datas: &[u8]) -> Hash

Compute SHA256 hash of any binary datas

pub fn compute_multipart(data_parts: &[&[u8]]) -> Hash

Compute SHA256 hash of any binary data on several parts

pub fn compute_blake3(datas: &[u8]) -> Hash

Compute BLAKE3 hash of any binary datas

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

Convert Hash into bytes vector

pub fn to_hex(&self) -> String

Convert a Hash to an hex string.

pub fn from_hex(text: &str) -> Result<Hash, BaseConversionError>

Convert a hex string in a Hash.

The hex string must only contains hex characters and produce a 32 bytes value.

pub const fn max() -> Hash

Return tha maximum hash value

Hexadecimal representation is FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF

Trait Implementations

impl AsBytes for Hash

fn as_bytes(&self) -> &[u8]

Get the bytes of this value.

fn as_bytes_mut(&mut self) -> &mut [u8]

where Self: FromBytes,

Get the bytes of this value mutably.

impl AsRef<[u8]> for Hash

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Hash

fn clone(&self) -> Hash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Hash

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

Formats the value using the given formatter.

impl Default for Hash

fn default() -> Hash

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Hash

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Hash

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

Formats the value using the given formatter.

impl FromStr for Hash

type Err = BaseConversionError

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 Hash

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 Hash

fn cmp(&self, other: &Hash) -> 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 Hash

fn eq(&self, other: &Hash) -> 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 Hash

fn partial_cmp(&self, other: &Hash) -> 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 Hash

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Hash

impl Eq for Hash

impl FromBytes for Hash

impl StructuralPartialEq for Hash
