Memory

An in-memory Stash that is backed by another Stash but serves read requests from its memory. Write requests are propogated to the other Stash.

Postgres

A Stash whose data is stored in a Postgres database. The format of the tables are not specified and should not be relied upon. The only promise is stability. Any changes to the table schemas will be accompanied by a clear migration path.

Sqlite

A Stash whose data is stored in a single file on disk. The format of this file is not specified and should not be relied upon. The only promise is stability. Any changes to the on-disk format will be accompanied by a clear migration path.

StashCollection

StashCollection is like a differential dataflow Collection, but the state of the collection is durable.

StashError

An error that can occur while interacting with a Stash.

TableTransaction

TableTransaction emulates some features of a typical SQL transaction over table for a StashCollection.

TypedCollection

A helper struct to prevent mistyping of a StashCollection’s name and k,v types.
