  1. newtype Identity a

    cql-io Database.CQL.IO

    Identity functor and monad. (a non-strict monad)

    Examples

    >>> fmap (+1) (Identity 0)
Identity 1

    >>> Identity [1, 2, 3] <> Identity [4, 5, 6]
Identity [1,2,3,4,5,6]

    >>> do
x <- Identity 10
y <- Identity (x + 5)
pure (x + y)
Identity 25

  2. Identity :: a -> Identity a

  3. data Identifier

    epub-metadata Codec.Epub.Data.Metadata

    package/metadata/dc:identifier tag

  4. Identifier :: Maybe String -> Maybe String -> Maybe String -> String -> Identifier

  5. class Idempotent (c :: k1 -> k1 -> k)

    gdp Logic.Classes

    A binary operation # is idempotent if x # x == x for all x. The Idempotent c typeclass provides a single method, idempotent :: Proof (c p p == p). Within the module where F is defined, you can declare F to be idempotent with an empty instance: 

    -- Define an idempotent binary operation
data Union x y
instance Idempotent Union

  6. data IdSurgery (a :: k -> Type) (b :: k -> Type)

    generic-data-surgery Generic.Data.Surgery

    The identity surgery: doesn't do anything.

  7. data IdSurgery (a :: k -> Type) (b :: k -> Type)

    generic-data-surgery Generic.Data.Surgery.Internal

    The identity surgery: doesn't do anything.

  8. data Identity

    gitlab-haskell GitLab.Types

    identity

  9. Identity :: Text -> Text -> Maybe Int -> Identity

    gitlab-haskell GitLab.Types

    No documentation available.

  10. module Graphula.Idempotent

    A version of GraphulaT that removes all inserted data afterward
