Struct FastStableHasher 

pub struct FastStableHasher { /* private fields */ }

Trait Implementations

impl Clone for FastStableHasher

fn clone(&self) -> FastStableHasher

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FastStableHasher

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

Formats the value using the given formatter.

impl Hash for FastStableHasher

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 PartialEq for FastStableHasher

fn eq(&self, other: &FastStableHasher) -> 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 StableHasher for FastStableHasher

type Out = u128

The type of value returned when finishing

type Addr = u128

The type used when identifying where a value is located in a struct

type Bytes = [u8; 32]

Used when serializing

fn new() -> Self

Create an empty hasher

fn mixin(&mut self, other: &Self)

Adds all fields from another hasher

fn unmix(&mut self, other: &Self)

Removes all fields from another hasher

fn to_bytes(&self) -> Self::Bytes

Serialize

fn from_bytes(bytes: Self::Bytes) -> Self

Deserialize

fn write(&mut self, field_address: Self::Addr, bytes: &[u8])

Add a single field to the hash

fn finish(&self) -> u128

Finalize the digest
