Lib.rs

An implementation of serde::Serializer serializing directly into a hash digest (anything implementing digest::Update).

use digest::Digest;
use k256::ecdsa::SigningKey;
use serde::Serialize;
use sha2::Sha256;

use hashing_serializer::HashingSerializer;

let sk = SigningKey::from_slice(&[1u8; 32]).unwrap();
let vk = sk.verifying_key();

let mut digest = Sha256::new();
let serializer = HashingSerializer { digest: &mut digest };
vk.serialize(serializer).unwrap();
