Currently, all methods declared in the Georm trait are available. If a struct has an ID pointing towards another entity, the user can create a get method to get the entity pointed at from the database too (local one-to-one relationship). I still need to implement remote one-to-one relationships (one-to-one relationships when the ID of the remote object is not available locally). I still need to also test and debug one-to-many relationships (ID of the remote entiies not available locally) and many-to-many relationships (declared in a dedicated table). For now, IDs in all cases are simple types recognized by SQLx that are not arrays. Options are only supported when explicitely specified for one-to-one relationships.
