Struct casper_node::crypto::hash::Digest

pub struct Digest(_);

The hash digest; a wrapped u8 array.

Implementations

impl Digest

pub const LENGTH: usize

Length of Digest in bytes.

pub fn to_array(&self) -> [u8; 32]

Returns a copy of the wrapped u8 array.

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

Returns a copy of the wrapped u8 array as a Vec

pub fn from_hex<T: AsRef<[u8]>>(hex_input: T) -> Result<Self, Error>

Returns a Digest parsed from a hex-encoded Digest.

Trait Implementations

impl AsRef<[u8]> for Digest

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

Performs the conversion.

impl Clone for Digest

fn clone(&self) -> Digest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Digest

impl DataSize for Digest

const IS_DYNAMIC: bool

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

impl Debug for Digest

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

Formats the value using the given formatter.

impl Default for Digest

fn default() -> Digest

Returns the "default value" for a type.

impl<'de> Deserialize<'de> for Digest

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Display for Digest

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

Formats the value using the given formatter.

impl Eq for Digest

impl From<[u8; 32]> for Digest

fn from(inner: [u8; 32]) -> Self

Performs the conversion.

impl From<Blake2bHash> for Digest

fn from(blake2bhash: Blake2bHash) -> Self

Performs the conversion.

impl From<Digest> for Blake2bHash

fn from(digest: Digest) -> Self

Performs the conversion.

impl From<Digest> for BlockHash

fn from(digest: Digest) -> Self

Performs the conversion.

impl From<Digest> for DeployHash

fn from(digest: Digest) -> Self

Performs the conversion.

impl FromBytes for Digest

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

Deserializes the slice into Self.

fn from_vec(bytes: Vec<u8>) -> Result<(Self, Vec<u8>), Error>

Deserializes the Vec<u8> into Self.

impl Hash for Digest

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, 

Feeds a slice of this type into the given Hasher.

impl LowerHex for Digest

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

Formats the value using the given formatter.

impl Ord for Digest

fn cmp(&self, other: &Digest) -> 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<Digest> for Digest

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

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

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

This method tests for !=.

impl PartialOrd<Digest> for Digest

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

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

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

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

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

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

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

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

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

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

impl Serialize for Digest

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

Serialize this value into the given Serde serializer.

impl StructuralEq for Digest

impl StructuralPartialEq for Digest

impl ToBytes for Digest

fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

fn into_bytes(self) -> Result<Vec<u8>, Error>

Consumes self and serializes to a Vec<u8>.

impl<'_> TryFrom<&'_ [u8]> for Digest

type Error = TryFromSliceError

The type returned in the event of a conversion error.

fn try_from(slice: &[u8]) -> Result<Digest, Self::Error>

Performs the conversion.

impl UpperHex for Digest

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

Formats the value using the given formatter.
