| # ProtoDataStore C++ |
| |
| A simple file-backed proto with an in-memory cache. |
| |
| ## Features |
| |
| 1. Caches proto in RAM after first read for performance. |
| 1. Uses a checksum to verify integrity of data. |
| 1. Leverages modern [Abseil](https://abseil.io/) error handling and memory management. |
| |
| ## Usage |
| |
| ``` c++ |
| #include "protostore/file-storage.h" |
| #include "protostore/proto-data-store.h" |
| |
| FileStorage storage; |
| ProtoDataStore<TestProto> pds(storage, testfile); |
| |
| MyProto myproto; |
| myproto.set_value("hi"); |
| absl::Status result = pds.Write(myproto); |
| if (!result.ok()) // error handling |
| ``` |
| |
| ## Compared to Jetpack DataStore |
| |
| This library is a C++ implementation from the same origin as [Jetpack DataStore](https://developer.android.com/topic/libraries/architecture/datastore). Unlike that library, it does not support concurrent writes and the on-disk format |
| is incompatible. |
