data Promise a
Promises are used for referencing the results of future runtime computations during load time splice processing.
newEmptyPromise :: HeistT n IO (Promise a)
Creates an empty promise.
getPromise :: Monad n => Promise a -> RuntimeSplice n a
Gets the result of a promised runtime computation.
putPromise :: Monad n => Promise a -> a -> RuntimeSplice n ()
Adds a promise to the runtime splice context.
adjustPromise :: Monad n => Promise a -> (a -> a) -> RuntimeSplice n ()
Modifies a promise.
