Savepoint

Savepoint is a lightweight ORM-style serialization framework for C++ applications. Inspired by cereal and built on databases like SQLite, it provides a simple interface for saving and loading C++ objects.

Features

• Automatic transactions and schema upgrades
• Entity IDs and 2D/3D spatial keys
• Inherited, nested, polymorphic members and types
• Smart pointers, containers, tuples, random generators, etc
• Portable saves across platforms
• Opt-in thread safety and concurrent SQLite connections
• Integrated visual debugger

Entity inEntity{"Player", {1, 2, 3}, 0.5f};
savepoint.Write(inEntity, 0);
savepoint.Read<Entity>([&](Entity& outEntity)
{
assert(outEntity == inEntity);
}, 0);
savepoint.Close();
return0;
}
