Interface UtilServiceGrpc.AsyncService

All Known Implementing Classes:
UtilServiceGrpc.UtilServiceImplBase
Enclosing class:
UtilServiceGrpc
public static interface UtilServiceGrpc.AsyncService

 The Utility Service provides a pseudo-random number generator.
 The single gRPC call defined for this service simply reports a single
 pseudo-random number in the transaction record. That value may either
 be a 32-bit integer within a requested range, or a 384-bit byte array.
 ### Block Stream Effects
 The requested value is reported exclusively in a `UtilPrngOutput` message.
