data All

Select all indices at a certain position.

Constructors

Instances

Slice sl => Slice ((:.) sl All)
type SliceShape ((:.) sl All) = (:.) (SliceShape sl) Int
type FullShape ((:.) sl All) = (:.) (FullShape sl) Int

data Any sh

Place holder for any possible shape.

Constructors

Instances

type family FullShape ss

Map a type of the index in the full shape, to the type of the index in the slice.

Instances

type FullShape Z = Z
type FullShape (Any sh) = sh
type FullShape ((:.) sl All) = (:.) (FullShape sl) Int
type FullShape ((:.) sl Int) = (:.) (FullShape sl) Int

type family SliceShape ss

Map the type of an index in the slice, to the type of the index in the full shape.

Instances

type SliceShape Z = Z
type SliceShape (Any sh) = sh
type SliceShape ((:.) sl All) = (:.) (SliceShape sl) Int
type SliceShape ((:.) sl Int) = SliceShape sl

class Slice ss where

Class of index types that can map to slices.

Methods
