Struct fog_pack::crypto::Hash

pub struct Hash { /* fields omitted */ }

Crytographically secure hash of data. Can be signed by a FullKey. It is impractical to generate an identical hash from different data.

Supported Versions

• 0: Null hash. Used to refer to hash of parent document
• 1: Blake2B hash with 32 bytes of digest

Implementations

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

pub fn len(&self) -> usize

pub fn encode(&self, buf: &mut Vec<u8>)

Formats the value using the given formatter.

impl Eq for Hash

impl From<Hash> for Value

fn from(v: Hash) -> Self

Performs the conversion.

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,

impl LowerHex for Hash

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

impl Ord for Hash

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

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Hash> for Hash

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

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

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<Hash> for Hash

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

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

#[must_use]fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]fn le(&self, other: &Rhs) -> bool

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

#[must_use]fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]fn ge(&self, other: &Rhs) -> bool

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

impl UpperHex for Hash

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

Formats the value using the given formatter.
