Struct Hash

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

A wrapper type for using a hash an internal key

Methods from Deref<Target = InternalKey<32>>

pub fn get_bit(&self, i: usize) -> bool

pub fn fork_height(&self, key: &InternalKey<N>) -> usize

Treat InternalKey as a path in a tree fork height is the number of common bits(from higher to lower) of two InternalKeys

pub fn parent_path(&self, height: usize) -> Self

Treat InternalKey as a path in a tree return parent_path of self

pub fn copy_bits(&self, range: impl RangeBounds<usize>) -> Self

Copy bits and return a new InternalKey

Trait Implementations

impl BorshDeserialize for Hash

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

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.

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

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for Hash

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

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 Deref for Hash

type Target = InternalKey<32>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl From<[u8; 32]> for Hash

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

Converts to this type from the input type.

impl From<H256> for Hash

fn from(hash: H256) -> Self

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 Key<32> for Hash

type Error = Error

The error type for failed mappings

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

This should map from the internal key space back into the user’s key space

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

This should map from the user’s key space into the internal keyspace

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

This should map from the internal key space back into the user’s key space

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.
