Struct StableHasher 

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

Stable, secure hasher.

Important

Do not call the Hasher::finish method. It will panic. Use StableHasher::finalize instead.

Implementations

impl StableHasher

pub fn new() -> StableHasher

Create a new stable hasher

pub fn hash_one<T>(value: &T) -> u128

where T: Hash,

Hash one value

pub const fn const_hash(value: &[u8]) -> u128

Hash a byte slice in a const context. Slower than the non-const version, so only use when const can be guaranteed.

pub fn finalize(&self) -> u128

Finalize and return the hash

Methods from Deref<Target = Xxh3Default>

pub fn reset(&mut self)

Resets state

pub fn update(&mut self, input: &[u8])

Hashes provided chunk

pub fn digest(&self) -> u64

Computes hash.

pub fn digest128(&self) -> u128

Computes hash as 128bit integer.

Trait Implementations

impl Default for StableHasher

fn default() -> StableHasher

Returns the “default value” for a type.

impl Deref for StableHasher

type Target = Xxh3Default

The resulting type after dereferencing.

fn deref(&self) -> &<StableHasher as Deref>::Target

Dereferences the value.

impl DerefMut for StableHasher

fn deref_mut(&mut self) -> &mut <StableHasher as Deref>::Target

Mutably dereferences the value.
