Description |
The identity functor and monad.
This trivial type constructor serves two purposes:
- It can be used with functions parameterized by a Functor or Monad.
- It can be used as a base monad to which a series of monad
transformers may be applied to construct a composite monad.
Most monad transformer modules include the special case of
applying the transformer to Identity. For example, State s
is an abbreviation for StateT s Identity.
