Implementations

impl Hash

pub fn new(hash_slice: &[u8]) -> Self

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

pub fn new_unique() -> Self

unique Hash for tests and benchmarks.

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

Trait Implementations

impl AbiExample for Hash

fn example() -> Self

impl AsRef<[u8]> for Hash

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

Performs the conversion.

impl BorshDeserialize for Hash

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

pub fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

pub fn is_u8() -> bool

Whether Self is u8. NOTE: Vec<u8> is the most common use-case for serialization and deserialization, it’s worth handling it as a special case to improve performance. It’s a workaround for specific Vec<u8> implementation versus generic Vec<T> implementation. See https://github.com/rust-lang/rfcs/pull/1210 for details.

impl BorshSchema for Hash where
    [u8; 32]: BorshSchema, 

fn declaration() -> Declaration

Get the name of the type without brackets.

fn add_definitions_recursively(
    definitions: &mut HashMap<Declaration, Definition>
)

Recursively, using DFS, add type definitions required for this type. For primitive types this is an empty map. Type definition explains how to serialize/deserialize a type.

pub fn add_definition(
    declaration: String,
    definition: Definition,
    definitions: &mut HashMap<String, Definition, RandomState>
)

Helper method to add a single type definition to the map.

pub fn schema_container() -> BorshSchemaContainer

impl BorshSerialize for Hash

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

pub fn try_to_vec(&self) -> Result<Vec<u8, Global>, Error>

Serialize this instance into a vector of bytes.

pub fn is_u8() -> bool

Whether Self is u8. NOTE: Vec<u8> is the most common use-case for serialization and deserialization, it’s worth handling it as a special case to improve performance. It’s a workaround for specific Vec<u8> implementation versus generic Vec<T> implementation. See https://github.com/rust-lang/rfcs/pull/1210 for details.

impl Clone for Hash

fn clone(&self) -> Hash

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Hash

impl Debug for Hash

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

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

Formats the value using the given formatter.

impl Eq for Hash

impl FromStr for Hash

type Err = ParseHashError

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.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

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.

#[must_use]

pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]

pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]

pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Hash> for Hash

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

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

fn ne(&self, other: &Hash) -> 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]

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

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

#[must_use]

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

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