gpg::EndpointDiscoveryListenerHelper
#include <endpoint_discovery_listener_helper.h>
定义了一个辅助程序，可用于向 SDK 提供 IEndpointDiscoveryListener 回调，而无需定义完整的 IEndpointDiscoveryListener 接口。
摘要
系统会调用在此对象上配置的回调，如 Nearby Connections API 中所述。未明确设置的回调将不执行任何操作。

typedef
std::function< void(int64_t client_id, const EndpointDetails &endpoint_details)>
找到远程端点时，系统会调用 OnEndpointFoundCallback。 |
OnEndpointLostCallback
|
typedef
std::function< void(int64_t client_id, const std::string &remote_endpoint_id)>
当远程端点无法再被发现时，系统会调用 OnEndpointLostCallback。 |

OnEndpointFoundCallback
std::function< void(int64_t client_id, const EndpointDetails &endpoint_details)> OnEndpointFoundCallback
找到远程端点时，系统会调用 OnEndpointFoundCallback。
client_id 是发现端点的 NearbyConnections 实例的 ID。endpoint_details 包含发现的远程端点的详细信息。
OnEndpointLostCallback
std::function< void(int64_t client_id, const std::string &remote_endpoint_id)> OnEndpointLostCallback
当远程端点无法再被发现时，系统会调用 OnEndpointLostCallback。
