Struct SipHasher

pub struct SipHasher { /* private fields */ }

A fast, non-cryptographic hash outputting 128-bit digests.

This implementation is used as the default Hasher implementation, using the standard library Hash trait, which may produce non-portable hashes as described in the documentation of the Hash trait itself, and this crate’s Hasher.

Users may choose to initialise the SipHasher with seed keys if untrusted key/value user input is used in a tree in order to prevent chosen-hash collision attacks.

Implementations

impl SipHasher

pub fn new(key: &[u8; 16]) -> Self

Initialise a SipHasher with the provided seed key.

All peers comparing tree hashes MUST be initialised with the same seed key.

Trait Implementations

impl Clone for SipHasher

fn clone(&self) -> SipHasher

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SipHasher

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

Formats the value using the given formatter.

impl Default for SipHasher

fn default() -> SipHasher

Returns the “default value” for a type.

impl<T> Hasher<16, T> for SipHasher

where T: Hash,

fn hash(&self, value: &T) -> Digest<16>

Hash T, producing a unique, deterministic digest of N bytes length.
