connectionForRequest method

Future<RelayConnectivity?> connectionForRequest(RequestState state, RelayConnectivity picked, { ConnectionSource connectionSource = ConnectionSource.explicit, })

The connection state must go out on towards the relay an engine picked.

picked is that relay's anonymous connection, which is how engines discover relays. A request that requires an identity gets its own bound connection instead, opened if it is not there yet. Null means the request must not be sent to that relay at all: falling back to picked is exactly what the caller ruled out.

Implementation

Future<RelayConnectivity?> connectionForRequest(
  RequestState state,
  RelayConnectivity picked, {
  ConnectionSource connectionSource = ConnectionSource.explicit,
}) async {
  final auth = state.request.auth;
  if (auth is! RelayAuthRequire) {
    return picked;
  }
  if (!auth.account.signer.canSign()) {
    Logger.log.w(
      () => "${state.id} requires ${auth.account.pubkey}, which cannot sign",
    );
    return null;
  }
  return openConnectionAs(
    picked.url,
    auth.account,
    connectionSource: connectionSource,
  );
}
