Combinators to "make" generic functions via cast
mkT :: (Rep a, Rep b) => (b -> b) -> a -> a Source #
Make a generic transformation; start from a type-specific case; preserve the term otherwise
mkQ :: (Rep a, Rep b) => r -> (b -> r) -> a -> r Source #
Make a generic query; start from a type-specific case; return a constant otherwise
mkM :: (Monad m, Rep a, Rep b) => (b -> m b) -> a -> m a Source #
Make a generic monadic transformation; start from a type-specific case; resort to return otherwise
mkMp :: (MonadPlus m, Rep a, Rep b) => (b -> m b) -> a -> m a Source #
Make a generic monadic transformation for MonadPlus; use "const mzero" (i.e., failure) instead of return as default.
mkR :: (MonadPlus m, Rep a, Rep b) => m b -> m a Source #
Make a generic builder; start from a type-specific ase; resort to no build (i.e., mzero) otherwise
extT :: (Rep a, Rep b) => (a -> a) -> (b -> b) -> a -> a Source #
Extend a generic transformation by a type-specific case
extQ :: (Rep a, Rep b) => (a -> q) -> (b -> q) -> a -> q Source #
Extend a generic query by a type-specific case
extM :: (Monad m, Rep a, Rep b) => (a -> m a) -> (b -> m b) -> a -> m a Source #
Extend a generic monadic transformation by a type-specific case
extMp :: (MonadPlus m, Rep a, Rep b) => (a -> m a) -> (b -> m b) -> a -> m a Source #
Extend a generic MonadPlus transformation by a type-specific case
Type synonyms for generic function types
type GenericT = forall a. Rep a => a -> a Source #
Generic transformations, i.e., take an "a" and return an "a"
type GenericQ r = forall a. Rep a => a -> r Source #
Generic queries of type "r", i.e., take any "a" and return an "r"
type GenericM m = forall a. Rep a => a -> m a Source #
Generic monadic transformations, i.e., take an "a" and compute an "a"
type GenericR m = forall a. Rep a => m a Source #
Generic readers, say monadic builders, i.e., produce an "a" with the help of a monad "m".
type Generic c = forall a. Rep a => a -> c a Source #
The general scheme underlying generic functions assumed by gfoldl; there are isomorphisms such as GenericT = Generic T.
Wrapped generic functions; recall: [Generic c] would be legal but [Generic' c] not.
