impl EncodeLike for Digest
impl Eq for Digest
impl StorageAppend<DigestItem> for Digest
We abuse the fact that SCALE does not put any marker into the encoding, i.e. we only encode the
internal vec and we can append to this vec. We have a test that ensures that if the Digest
format ever changes, we need to remove this here.
