Struct RawHasher

pub struct RawHasher<S>(/* private fields */);

Available on crate feature xxhash3_128 only.

A lower-level interface for computing a hash from streaming data.

The algorithm requires a secret which can be a reasonably large piece of data. Hasher makes one concrete implementation decision that uses dynamic memory allocation, but specialized usages may desire more flexibility. This type, combined with SecretBuffer, offer that flexibility at the cost of a generic type.

Implementations

impl<S> RawHasher<S>

pub fn new(secret_buffer: SecretBuffer<S>) -> Self

Construct the hasher with the provided seed, secret, and temporary buffer.

pub fn into_secret(self) -> S

Returns the secret.

impl<S> RawHasher<S>

where S: FixedBuffer,

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

Writes some data into this Hasher.

pub fn finish_128(&self) -> u128

Returns the hash value for the values written so far. Unlike std::hash::Hasher::finish, this method returns the complete 128-bit value calculated, not a 64-bit value.

Trait Implementations

impl<S: Clone> Clone for RawHasher<S>

fn clone(&self) -> RawHasher<S>

Returns a copy of the value.

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

Performs copy-assignment from source.
