Struct RawHasher

pub struct RawHasher<S> { /* private fields */ }

Available on crate feature xxhash3_64 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.
