traverse :: forall f t a. Coercible (f a) (f t) => Newtype t a => (a -> t) -> (a -> f a) -> t -> f t

traverse :: forall r rl rlo ri ro r1 r2 r3 a b m. RowToList r rl => VariantFTraverseCases m rl ri ro a b => RowToList ro rlo => VariantTags rlo => VariantFMaps rlo => Union ri r2 r1 => Union ro r2 r3 => Applicative m => Traversable (VariantF r2) => Record r -> (a -> m b) -> VariantF r1 a -> m (VariantF r3 b)

Traverse over some labels (with access to the containers) and use traverse f for the rest (just changing the index type).

traverse r f is like (traverse f >>> expand) # traverseSome r but with a more easily solved constraint (i.e. it can be solved once the type of r is known).

traverse :: forall r rl ri ro r1 r2 r3 m. RowToList r rl => VariantTraverseCases m rl ri ro => Union ri r2 r1 => Union ro r2 r3 => Applicative m => Record r -> Variant r1 -> m (Variant r3)

Traverse over some labels and leave the rest unchanged. (Implemented by expanding after traverseSome.)

traverse :: forall a t. TypedArray a t => (t -> Effect t) -> ArrayView a -> Effect (ArrayView a)

Traverses over each value, returning a new one.

traverse :: forall a b m. MonadRec m => (b -> a -> m b) -> b -> Producer a m Unit -> m b

Fold every value produced with a monadic action

Uses MonadRec, supporting producers of arbitrary length.

traverse :: forall m p q a b. Dissect p q => MonadRec m => (a -> m b) -> p a -> m (p b)

A tail-recursive traverse operation, implemented in terms of Dissect.
