Description

Synopsis

Documentation

class Profunctor p => Bizarre p w | w -> p where Source

This class is used to run the various Bazaar variants used in this library.

Methods

bazaar :: Applicative f => p a (f b) -> w a b t -> f t Source

Instances

Profunctor p => Bizarre p (Bazaar p)
Methods bazaar :: Applicative f => p a (f b) -> Bazaar p a b t -> f t Source
Profunctor p => Bizarre p (BazaarT p g)
Methods bazaar :: Applicative f => p a (f b) -> BazaarT p g a b t -> f t Source
Corepresentable p => Bizarre p (TakingWhile p g)
Methods bazaar :: Applicative f => p a (f b) -> TakingWhile p g a b t -> f t Source
Bizarre (Indexed Int) Mafic
Methods bazaar :: Applicative f => Indexed Int a (f b) -> Mafic a b t -> f t Source
Bizarre (Indexed i) (Molten i)
Methods bazaar :: Applicative f => Indexed i a (f b) -> Molten i a b t -> f t Source

newtype Bazaar p a b t Source

This is used to characterize a Traversal.

a.k.a. indexed Cartesian store comonad, indexed Kleene store comonad, or an indexed FunList.

http://twanvl.nl/blog/haskell/non-regular1

A Bazaar is like a Traversal that has already been applied to some structure.

Where a Context a b t holds an a and a function from b to t, a Bazaar a b t holds N as and a function from N bs to t, (where N might be infinite).

Mnemonically, a Bazaar holds many stores and you can easily add more.

This is a final encoding of Bazaar.

type Bazaar' p a = Bazaar p a a Source

This alias is helpful when it comes to reducing repetition in type signatures.

type Bazaar' p a t = Bazaar p a a t

newtype BazaarT p g a b t Source

BazaarT is like Bazaar, except that it provides a questionable Contravariant instance To protect this instance it relies on the soundness of another Contravariant type, and usage conventions.

For example. This lets us write a suitably polymorphic and lazy taking, but there must be a better way!
