Cardano.Wallet.DB.Pure.Layer
Description
Dummy implementation of the database-layer, using
MVar
. This may be good
for testing to compare with an implementation on a real data store, or to use
when compiling the wallet for targets which don't have SQLite.
Synopsis
- newDBLayer :: forall m s k. ( MonadUnliftIO m, MonadFail m) => TimeInterpreter Identity -> m ( DBLayer m s k)
Documentation
newDBLayer :: forall m s k. ( MonadUnliftIO m, MonadFail m) => TimeInterpreter Identity -> m ( DBLayer m s k) Source #
Instantiate a new in-memory "database" layer that simply stores data in a local MVar. Data vanishes if the software is shut down.
