Exact lookup

1. lookupName :: forall (n :: S) a . Name n -> NameMap n a -> a

   free-foil	Control.Monad.Foil

   Looking up a name should always succeed. Note that since Name is Sinkable, you can lookup a name from scope n in a NameMap for scope l whenever l extends n.

2. lookupSubst :: forall e (i :: S) (o :: S) . InjectName e => Substitution e i o -> Name i -> e o

   free-foil	Control.Monad.Foil

   Apply substitution to a given name.

3. lookupName :: forall (n :: S) a . Name n -> NameMap n a -> a

   free-foil	Control.Monad.Foil.Internal

   Looking up a name should always succeed. Note that since Name is Sinkable, you can lookup a name from scope n in a NameMap for scope l whenever l extends n.

4. lookupSubst :: forall e (i :: S) (o :: S) . InjectName e => Substitution e i o -> Name i -> e o

   free-foil	Control.Monad.Foil.Internal

   Apply substitution to a given name.

5. lookupNode :: Node -> NodeManager k -> Maybe k

   graph-core	Data.Core.Graph.NodeManager

   No documentation available.

6. lookupAs :: forall k (c :: Type -> Type) a . (PMapKey k, NonEmptyLike c, PMapValue k ~ a, FromGraphSON a) => k -> PMap c GValue -> Either PMapLookupException a

   greskell	Data.Greskell.AsLabel

   Lookup the value and parse it into a.

7. lookupAsM :: forall k (c :: Type -> Type) a m . (PMapKey k, NonEmptyLike c, PMapValue k ~ a, FromGraphSON a, MonadThrow m) => k -> PMap c GValue -> m a

   greskell	Data.Greskell.AsLabel

   MonadThrow version of lookupAs.

8. lookupM :: forall k (c :: Type -> Type) m v . (PMapKey k, NonEmptyLike c, MonadThrow m) => k -> PMap c v -> m v

   greskell	Data.Greskell.AsLabel

   MonadThrow version of lookup. If there is no value for the key, it throws PMapNoSuchKey.

9. lookupAs :: forall k (c :: Type -> Type) a . (PMapKey k, NonEmptyLike c, PMapValue k ~ a, FromGraphSON a) => k -> PMap c GValue -> Either PMapLookupException a

   greskell	Data.Greskell.Extra

   Lookup the value and parse it into a.

10. lookupAs' :: forall k (c :: Type -> Type) a . (PMapKey k, NonEmptyLike c, PMapValue k ~ Maybe a, FromGraphSON a) => k -> PMap c GValue -> Either PMapLookupException (Maybe a)

    greskell	Data.Greskell.Extra

    Similar to lookupAs, but this function converts a null result into Nothing. A null result is either (1) the key k is not found in the map, or (2) the key is found, but the value is null.
