  Failures are reported through the returned Status. The SDK converts internal exceptions into a non-OK Status; public API calls do not throw. Inspect status.IsOk() and status.Message() for failure details. See Status.

Example

#include "milvus/MilvusClientV2.h"
auto client = milvus::MilvusClientV2::Create();

milvus::ConnectParam connect_param{"http://localhost:19530", "root:Milvus"};
auto status = client->Connect(connect_param);
if (!status.IsOk()) {
    std::cout << status.Message() << std::endl;
}

status = client->GrantPrivilege(
    milvus::GrantPrivilegeRequest()
        .WithRoleName(role_name)
        .WithObjectType("Collection")
        .WithObjectName(collection_name)
        .WithPrivilege("Search")

if (!status.IsOk()) {
    std::cout << status.Message() << std::endl;
