lasso :: forall k v m h xs. (Monad m, Lookup xs k v, Wrapper h) => FieldName k -> TangleT xs h m (Repr h (k :> v)) Source #

Hitch an element associated to the FieldName through a wrapper.

hitchAt :: Monad m => Membership xs x -> TangleT xs h m (h x) Source #

Take a value from the tangles. The result is memoized.

runTangleT :: Monad m => (xs :& Comp (TangleT xs h m) h) -> (xs :& Nullable h) -> TangleT xs h m a -> m (a, xs :& Nullable h) Source #

Run a TangleT action and return the result and the calculated values.

evalTangleT :: Monad m => (xs :& Comp (TangleT xs h m) h) -> (xs :& Nullable h) -> TangleT xs h m a -> m a Source #

Run a TangleT action.

runTangles :: Monad m => (xs :& Comp (TangleT xs h m) h) -> (xs :& Nullable h) -> m (xs :& h) Source #

Run tangles and collect all the results as a Record.
