Struct Hash

pub struct Hash(/* private fields */);

Implementations

impl Hash

pub fn digest(bytes: Bytes) -> Self

Enter an array of bytes to get a 32-bit hash. Note: sha3 is used for the time being and may be replaced with other hashing algorithms later.

pub fn from_empty() -> Self

pub fn from_bytes(bytes: Bytes) -> ProtocolResult<Self>

Converts the byte array to a Hash type. Note: if you want to compute the hash value of the byte array, you should call fn digest.

pub fn from_hex(s: &str) -> ProtocolResult<Self>

pub fn as_bytes(&self) -> Bytes

pub fn as_hex(&self) -> String

Trait Implementations

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

Formats the value using the given formatter.

impl Decodable for Hash

Decode a value from RLP bytes

impl Default for Hash

fn default() -> Self

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 Encodable for Hash

fn rlp_append(&self, s: &mut RlpStream)

Append a value to the stream

fn rlp_bytes(&self) -> Vec<u8>

Get rlp-encoded bytes for this instance

impl FixedCodec for Hash

fn encode_fixed(&self) -> ProtocolResult<Bytes>

fn decode_fixed(bytes: Bytes) -> ProtocolResult<Self>

impl From<Hash> for Hash

fn from(hash: Hash) -> Hash

Converts to this type from the input type.

impl From<Hash> for MerkleRoot

fn from(root: MerkleRoot) -> MerkleRoot

Converts to this type from the input 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 TryFrom<Hash> for Hash

type Error = ProtocolError

The type returned in the event of a conversion error.

fn try_from(hash: Hash) -> Result<Hash, Self::Error>

Performs the conversion.

impl Eq for Hash
