Types

type Memory

type Memory struct {
	Bag map[ld.Link][]byte
}

Memory is a simple in-memory storage for data indexed by ld.Link. (It's little more than a map -- in fact, the map is exported, and you can poke it directly.)

The OpenRead method conforms to ld.BlockReadOpener, and the OpenWrite method conforms to ld.BlockWriteOpener. Therefore it's easy to use in a LinkSystem like this:

store := storage.Memory{}
lsys.StorageReadOpener = (&store).OpenRead
lsys.StorageWriteOpener = (&store).OpenWrite

This storage is mostly expected to be used for testing and demos, and as an example of how you can implement and integrate your own storage systems.
