Foundation.Tuple.Nth

Description

a Generalized version of Fstable, Sndable, ..

Using this module is limited to GHC 7.10 and above.

Synopsis

class KnownNat n => Nthable n a where
- type NthTy n a
- nth :: proxy n -> a -> NthTy n a

Documentation

class KnownNat n => Nthable n a where Source #

A generalized version of indexed accessor allowing access to tuples n'th element.

Indexing starts at 1, as fst is used to get first element.

Associated Types

type NthTy n a Source #

Methods

nth :: proxy n -> a -> NthTy n a Source #
