Struct meowhash::MeowHash

pub struct MeowHash { /* fields omitted */ }

A hash produced by the MeowHasher.

It consists of 8 128-bit SIMD register values, 128 bytes in total. You can distill it into a u128 or use the entire 128 byte hash.

It's recommended to keep the MeowHash instead of converting it into an array of bytes, because MeowHashes can be compared efficiently using SIMD instructions where byte arrays may need a byte by byte comparison.

Methods

impl MeowHash

pub fn from_bytes(bytes: [u8; 128]) -> Self

Create a MeowHash from an array of 128 bytes.

pub fn from_slice(bytes: &[u8]) -> Option<Self>

Attempt to construct a MeowHash from a slice of bytes.

This will fail if the slice doesn't contain exactly 128 bytes.

pub fn into_bytes(self) -> [u8; 128]

Convert a MeowHash into an array of 128 bytes.

pub fn as_u128(&self) -> u128

Compress a MeowHash into a u128.

pub fn expand_seed(seed: &[u8]) -> Self

Construct a seed value from arbitrary length input data.

This can be an expensive operation, so try to only do it once.

pub fn default_seed() -> Self

Create a MeowHash containing the default seed (an encoding of pi).
