        fn update_sealing(&self);
        fn submit_seal(&self, block_hash: H256, seal: Vec<Bytes>);
        fn broadcast_consensus_message(&self, message: Bytes);
    }

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
