Are the derives on model types correct

[tcharding]

I can't remember why I used the current set of derives e.g,

/// Models the result of JSON-RPC method `getbestblockhash`.
#[derive(Clone, Debug, PartialEq, Deserialize, Serialize)]
pub struct GetBestBlockHash(pub BlockHash);

And

/// Models the result of JSON-RPC method `getblock` with verbosity set to 0.
#[derive(Clone, Debug, PartialEq, Eq, Deserialize, Serialize)]
pub struct GetBlockVerbosityZero(pub Block);

Why no Ord/PartialOrd, is Eq correct?
