Struct HashSecret 

pub struct HashSecret { /* private fields */ }

Implementations

impl HashSecret

pub fn new(seed: u32) -> Self

pub const fn from_keys(k0: u64, k1: u64) -> Self

Build a secret from explicit SipHash keys, bypassing seed derivation. Lets an embedder reproduce a fixed keying (e.g. a deterministic run) that new cannot express through its u32 seed.

pub fn hash_value<T: Hash + ?Sized>(&self, data: &T) -> PyHash

pub fn hash_iter<'a, T: 'a, I, F, E>( &self, iter: I, hash_func: F, ) -> Result<PyHash, E>

where I: IntoIterator<Item = &'a T>, F: Fn(&'a T) -> Result<PyHash, E>,

pub fn hash_bytes(&self, value: &[u8]) -> PyHash

pub fn hash_str(&self, value: &str) -> PyHash
