"""

This is a Nexus service definition that demonstrates multiple argument handling.

A service definition defines a Nexus service as a named collection of operations, each

with input and output types. It does not implement operation handling: see the service

handler and operation handlers in nexus_multiple_args.handler.service_handler for that.

A Nexus service definition is used by Nexus callers (e.g. a Temporal workflow) to create

type-safe clients, and it is used by Nexus handlers to validate that they implement

correctly-named operation handlers with the correct input and output types.

The service defined in this file features one operation: hello, where hello

demonstrates handling multiple arguments through a single input object.
