Struct autobahn_hash::AutobahnHasher

pub struct AutobahnHasher { /* private fields */ }

A hash instance.

For maximum performance, use this hasher in a larger code block compiled with SIMD target features enabled.

Implementations

impl AutobahnHasher

pub fn new() -> Self

Create a new AutobahnHasher.

pub fn new_with_key(key: [u64; 4]) -> Self

Create a new AutobahnHasher with the given key.

pub fn write_packet(&mut self, packet: [u64; 4])

Write a packet of data to the hasher.

pub fn write_bytes(&mut self, bytes: [u8; 32])

Write a packet of data to the hasher, in the form of bytes.

pub fn finish_64(self, remainder: &[u8]) -> u64

Produce a 64-bit hash.

The remainder bytes must be less than a packet (less than 32 bytes).

Writing the remainder is notably different than Hasher::write. The remainder is padded and permuted into a 32-byte packet.

Panics

Panics if remainder is not less than 32 bytes.

pub fn finish_128(self, remainder: &[u8]) -> [u64; 2]

Produce a 128-bit hash.

The remainder bytes must be less than a packet (less than 32 bytes).

Writing the remainder is notably different than Hasher::write. The remainder is padded and permuted into a 32-byte packet.

Panics

Panics if remainder is not less than 32 bytes.

pub fn finish_256(self, remainder: &[u8]) -> [u64; 4]

Produce a 256-bit hash.

The remainder bytes must be less than a packet (less than 32 bytes).

Writing the remainder is notably different than Hasher::write. The remainder is padded and permuted into a 32-byte packet.

Panics

Panics if remainder is not less than 32 bytes.
