Trait Implementations

impl Arbitrary for Hash

fn arbitrary<G: Gen>(g: &mut G) -> Self

fn shrink(&self) -> Box<dyn Iterator<Item = Self>, Global>

impl Arbitrary for Hash

type Parameters = ()

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = BoxedStrategy<Hash>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(args: <Self as Arbitrary>::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl AsRef<[u8]> for Hash

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

Converts this type into a shared reference of the (usually inferred) input type.

impl BlockId for Hash

fn zero() -> Hash

A special ID used to denote a non-existent block (e.g. the parent of the first block).

impl Clone for Hash

fn clone(&self) -> Hash

Returns a copy 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 Deserialize for Hash

fn deserialize<R: Read>(codec: &mut Codec<R>) -> Result<Self, ReadError>

fn deserialize_validate<R>(codec: &mut Codec<R>) -> Result<(), ReadError>where R: Read,

impl Display for Hash

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

Formats the value using the given formatter.

impl<'a> From<&'a Hash> for &'a [u8; 32]

fn from(h: &'a Hash) -> Self

Converts to this type from the input type.

impl From<[u8; 32]> for Hash

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

Converts to this type from the input type.

impl From<Blake2b256> for Hash

fn from(hash: Blake2b256) -> Self

Converts to this type from the input type.

impl From<Hash> for [u8; 32]

fn from(h: Hash) -> Self

Converts to this type from the input type.

impl FromStr for Hash

type Err = Error

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.

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) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<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: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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.

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

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

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

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

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

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

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 Serialize for Hash

fn serialized_size(&self) -> usize

Default implementation, not efficient, not recommended to use it

fn serialize<W: Write>(&self, codec: &mut Codec<W>) -> Result<(), WriteError>

fn serialize_as_vec(&self) -> Result<Vec<u8, Global>, WriteError>

Convenience method to serialize into a byte vector.
