Counting

data E Source #

Type-level names for the different kinds of slots counted in this library

The data constructors of this type are used in promoted form with -XDataKinds.

Constructors

ActiveSlotE	Active slots must be filled on the honest chain and may be filled on an alternative chain.
EmptySlotE	Empty slots may be filled on the honest chain and must not be filled on an alternative chain.
SlotE	`SlotE` is the union of `ActiveSlotE` and `EmptySlotE`

complementActive ∷ proxy pol → Size base SlotE → Count base (PreImage pol ActiveSlotE) which → Count base (PreImage pol EmptySlotE) which Source #

Every slot is either active or empty

complementEmpty ∷ proxy pol → Size base SlotE → Count base (PreImage pol EmptySlotE) which → Count base (PreImage pol ActiveSlotE) which Source #

Every slot is either active or empty

Slot

data S Source #

data Pol Source #

The polarity of a type

This is used to toggle how functions in this library interact with vectors of S values.

If the polarity is Inverted, then the function will treat all S values as if they were first complemented.

The PreImage type family does the corresponding parameterization of ActiveSlotE and EmptySlotE at the type level.

NOTE: No S value is ever actually complemented because of Inverted, but the functions parameterized by pol will treat them as if they were.
