Struct Hasher 

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

Streaming xxh3: feed pieces with Hasher::update; the digests equal the one-shot functions over the concatenation.

Implementations

impl Hasher

pub fn new() -> Self

An unseeded hasher.

pub fn with_seed(seed: u64) -> Self

A seeded hasher (matches xxh3_64_seeded).

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

Feed bytes.

pub fn field(&mut self, bytes: &[u8])

Feed one length-delimited field (its length, then its bytes), so adjacent fields can never run into each other ("ab","c" ≠ "a","bc").

pub fn digest64(&self) -> u64

64-bit digest of everything fed so far (the hasher stays usable).

pub fn digest128(&self) -> u128

128-bit digest of everything fed so far.

pub fn reset(&mut self)

Forget everything fed, keeping the seed.

Trait Implementations

impl Clone for Hasher

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Hasher

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

Formats the value using the given formatter.

impl Default for Hasher

fn default() -> Self

Returns the “default value” for a type.
