Expand description
Network service messages that clients or nodes send in order to use the services, communicate and carry out the tasks.
Variants
Cmd(DataCmd)
Messages that lead to mutation.
There will be no response to these messages on success, only if something went wrong. Due to the eventually consistent nature of the network, it may be necessary to continually retry operations that depend on the effects of mutations.
Query(DataQuery)
A read-only operation.
Senders should eventually receive either a corresponding QueryResponse
or an error in
reply.
QueryResponse
: Self::QueryResponse
QueryResponse
Fields
response: QueryResponse
The result of the query.
correlation_id: MessageId
ID of the query message.
The response to a query, containing the query result.
CmdError
An error response to a Cmd
.
ServiceError(ServiceError)
A message indicating that an error occurred as a node was handling a client’s message.
