Struct Hash 

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

A hash; the 32-byte output of a hashing algorithm.

This struct is used most often in solana-sdk and related crates to contain a SHA-256 hash, but may instead contain a blake3 hash.

Implementations

impl Hash

pub const fn new_from_array(hash_array: [u8; 32]) -> Hash

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

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

Trait Implementations

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 Copy for Hash

impl Debug for Hash

Available on crate feature decode only.

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<Hash, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

impl Eq for Hash

impl From<[u8; 32]> for Hash

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

Converts to this type from the input type.

impl FromStr for Hash

Available on crate feature decode only.

type Err = ParseHashError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Hash, <Hash as FromStr>::Err>

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

impl Hash for Hash

Custom impl of Hash for Hash.

This allows us to skip hashing the length of the hash which is always the same anyway.

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

where H: Hasher,

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

Equality operator ==.

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

Inequality operator !=.

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 Pod for Hash

impl Sanitize for Hash

Available on crate feature sanitize only.

fn sanitize(&self) -> Result<(), SanitizeError>

impl<'de, __WincodeConfig> SchemaRead<'de, __WincodeConfig> for Hash

where __WincodeConfig: Config,

const TYPE_META: TypeMeta

type Dst = Hash

fn read( reader: impl Reader<'de>, dst: &mut MaybeUninit<<Hash as SchemaRead<'de, __WincodeConfig>>::Dst>, ) -> Result<(), ReadError>

Read into dst from reader.

fn get(reader: impl Reader<'de>) -> Result<Self::Dst, ReadError>

Read Self::Dst from reader into a new Self::Dst.

impl<__WincodeConfig> SchemaWrite<__WincodeConfig> for Hash

where __WincodeConfig: Config,

const TYPE_META: TypeMeta

Metadata about the type’s serialization.

type Src = Hash

fn size_of( src: &<Hash as SchemaWrite<__WincodeConfig>>::Src, ) -> Result<usize, WriteError>

Get the serialized size of Self::Src.

fn write( writer: impl Writer, src: &<Hash as SchemaWrite<__WincodeConfig>>::Src, ) -> Result<(), WriteError>

Write Self::Src to writer.

fn from_bytes<'de>(bytes: &'de [u8], config: C) -> Result<&'de Self, ReadError>

where Self: Sized + SchemaRead<'de, C, Dst = Self>,
