Struct lfchring::Blake2bHasher

pub struct Blake2bHasher;

A Hasher implementation based on the BLAKE2b cryptographic hash function, as implemented in the blake2b_simd crate.

To use this Hasher implementation in lfchring-rs, the blake2b-hash crate feature must be enabled.

Examples

Assuming the blake2b-hash feature is enabled, a HashRing<N, H> that uses it can be initialized as shown below (for more initialization options, refer to the documentation of HashRing<N, H>):

use lfchring::{Blake2bHasher, HashRing, Result, Vnid};

const VIRTUAL_NODES_PER_NODE: Vnid = 2;
const REPLICATION_FACTOR: u8 = 3;

let ring: HashRing<str, Blake2bHasher> = HashRing::with_hasher(
    Blake2bHasher::default(),
    VIRTUAL_NODES_PER_NODE,
    REPLICATION_FACTOR
)?;
