executeQueryCardanoMode :: SocketPath -> NetworkId -> QueryInMode (Either EraMismatch result) -> ExceptT QueryConvenienceError IO result Source #

Execute a query against the local node. The local node must be in CardanoMode.

executeQueryAnyMode :: LocalNodeConnectInfo -> QueryInMode (Either EraMismatch result) -> ExceptT QueryConvenienceError IO result Source #

Execute a query against the local node in any mode.
