Syncer

Syncer is a tool to sync a struct between two programs over the network using GRPC.

WARNING

Do not use this project directly at the moment, the api is changing and all the needed tests have not been created.

Endpoint

Each struct that you want to sync needs an endpoint. Best way to sync multiple structs is to use a struct to combine the two for syncing. Struct tag extractor:"-" will block the field from being synced. All types besides interfaces can be created on the other side. As long as interfaces exist on the other side the data within will be updated but unless it is defined beforehand then the injector has no knowledge of the base type and cannot create it.
