Readme for effectful-data-cache-0.2.2.0

[back to package description]

effectful-data-cache

import Effectful
import Effectful.Cache
import Prelude hiding (lookup)

main :: IO ()
main = runEff . runCache Nothing $ do
  insert "key" (42 :: Int)
  v <- lookup @String @Int "key"
  liftIO $ print v

runCache creates a fresh store; runCacheWith wraps an existing Data.Cache.Cache so it can be shared with non-effectful code.
