Wouldn't it make sense to have it in a separate package?

[vmakhaev]

Yes, I think at least storages and types can be places to separate packages as soon project become a little bit mature.

And also swarm-storage package can include Storage base class and universal test suite for all storages. Maybe we can do the same for data types.

Indeed, as level-storage adds a non trivial dependency, it should ideally go into a separate package... Also, adding the level stuff into the default client bundle is a no-go. I'll cherry pick from this PR. On 19 Oct 2014 14:33, "Vladimir Makhaev" notifications@github.com wrote:

Merged. By the way, guys, do you know how to preserve history on merge? It says LevelStorage is a new file. https://github.com/gritzko/swarm/commit/9131847d4399ea0b150781df029885b4a021ef00
