pub struct Metadata { /* private fields */ }
Expand description
Node metadata. This can be constructed by providing some compatible frame_metadata
which is then decoded into this. We aim to preserve all of the existing information in
the incoming metadata while optimizing the format a little for Subxt’s use cases.
