context
context provides thread-indexed storage around arbitrary context
values. The interface supports nesting context values per thread, and at
any point, the calling thread may ask for their current context.
Synopsis
{-# LANGUAGE BlockArguments #-}
import qualified Context
data Thing = Thing
{ stuff :: Int
}
main :: IO ()
main = do
Context.withEmptyStore \store -> do
Context.use store Thing { stuff = 1 } do
Context.use store Thing { stuff = 2 } do
thing2 <- Context.mine store
-- ...
number1 <- Context.mines store stuff
